There is a temptation, in the second half of your thirties, to declare that you have "become bad at friendship," which is a convenient sentence because it applies to nearly everyone and absolves nearly everyone. It is not, strictly, true. What has happened is that you have become a person with a limited quantity of a specific currency, and you have not yet stopped spending it the way you did when you had more of it.
Friendship in your twenties runs on a different economy — an economy of surplus. Free hours. Free weekends. Sunday brunches that begin at eleven and end at four. There is a specific Sunday, somewhere in every twenties-city friendship, that seems in retrospect impossibly long, and that Sunday is the reason you both still call each other in a WhatsApp thread called "the girls" a decade later. You spent, on that Sunday, roughly seven hours of currency. Neither of you counted it.
The three denominations.
The currency of adult female friendship comes, as best I have been able to identify, in three denominations. They are not interchangeable. Learning which denomination a given friend needs at a given moment is the entire skill of being a good friend after thirty-two. In descending order of scarcity:
Time.
The most valuable. There is objectively less of it than there was, and there is not going to be more. Every hour you spend with a friend is an hour you have not spent alone with your own life. When your friend is thriving, an hour is a birthday-card kind of gift. When your friend is quietly collapsing, an hour is a small piece of a lifeboat. She will remember, ten years later, that you sat in her kitchen for three hours in the middle of a Tuesday afternoon and did not talk about your job. It cost you three hours. It bought you a friend for a decade.
Honesty.
The second denomination and, in some ways, the more difficult one, because honesty in female friendship is easily confused with either brutality or with a running commentary. What we are talking about is neither. It is: the specific sentence you say to your friend that she cannot say to herself. Not the sentence you have been sitting on for six weeks and finally cannot resist. The sentence you have been sitting on — because it needed sitting on — and are now delivering, precisely once, with the right weight. "I don't think you love him." "You should apply for that job." "This is the third time you've told me the same story about him. Notice it." One sentence, once, well-timed. That is honesty. The rest is opinion.
Presence.
The most portable, and therefore the one that gets counterfeited the most. Presence is not being in the same room. Presence is being in the same conversation. A friend who is texting you from her sofa while streaming three shows is not present, and the two of you are both counting the exchange in your minds as contact, when it is really only proximity. Presence is: the phone down; the browser closed; twenty minutes on a landline, if you had a landline. It is rare enough now, in most adult weeks, to be almost a ceremonial gift. Give it. She will notice.
You will lose a friendship not in a fight, but in a slow silence about the wrong currency being spent for a year and a half.
How to spend the currency well.
The first mistake, and it is nearly universal in women I have watched, including me, is to spend the currency evenly. To give each of your fifteen closest friends about a fifteenth of your available time, honesty and presence, and to feel, vaguely, that you are performing the role of a good friend. This is not how friendship works. It is how a fan club works.
The second mistake — corollary to the first — is to spend the currency in the wrong denomination. You send an old friend a long, honest text at 11 p.m. instead of getting on a train to see her; you sit in silence for three hours in a friend's kitchen when what she actually needed was one honest sentence about her fiancé; you show up in person for a friend who has been asking, for six months, for the smaller, quieter denomination of a Sunday phone call. This is a currency mis-match, and it happens more often than an actual falling out. Most drifts, in my experience, are three years of the wrong denomination in a row.
The Sunday audit.
Once a season, over coffee alone, name the four or five friends whose currency you spent this quarter, and be honest with yourself about which denomination you spent for each of them. Where you spent time, could you have spent presence? Where you spent honesty, was time what she was actually asking for? Where you spent presence — the sofa call, the twenty-minute walk — was it, actually, the right thing after all?
You will find, if you do this, that you have a shortlist of three or four friends whose currency you know how to spend — that is, whose denominations you know without asking — and a longer list of friends whose currency you have been spending for years in the wrong shape. The shortlist is the real friendship group. The longer list is the reason you are, on some Sundays, mildly and inexplicably exhausted.
The one line.
There is one line you can send to a friend, at any age, in any weather, in any denomination, and it will hold. It is not new. It is not clever. It is not literary. It is this: "I've been thinking about you. What's actually going on?"
"Thinking of you" would be the wrong denomination — thin, a little theatrical, easy to fake. The two extra words — "what's actually" — put the sentence into the correct one. It says: I have a currency. I have a limited amount of it. And I would like to spend it, specifically, on the truthful version of your Tuesday.
Send it. Once a week. To a different person. It is the closest thing I have found to a savings account in this economy.
