You Were Close as Children. You Aren’t Anymore.
Closeness between sisters at eight and eleven runs on logistics more than on anything either of them picked, one house, one set of adults setting the schedule, a fight at nine at night that's finished by breakfast because both of them need the same bathroom at seven. Neither one had to keep the relationship going, the contact happened whether or not anybody felt like having it, and what grew inside those conditions was real for as long as the conditions held.
Adulthood removes every one of them, a disagreement can run eleven months now because nobody has to walk past anybody's bedroom, a call can be ended and a separate life picked back up the same afternoon, and the relationship continues only if somebody decides every few weeks to make it continue. In most families one sister is doing that deciding, she calls first, she books the flights, and she's the one who drives the four hours when their mother has a scan.
Both women also kept developing after seventeen, which sounds obvious and stops being obvious the second it's applied to a sibling. The sister who knew her at fourteen knew her accurately at fourteen, and she can still be working from that information at forty-three because nothing in the years since has required her to update it. An older sister who made the decisions when they were children keeps making them about their mother's care and expects agreement, a younger sister who was treated as the one who can't handle anything gets left off the paperwork and then gets criticized for not helping.
Differences like these stay theoretical until a parent needs care, and then the question is who takes the unpaid Tuesday off work, whose card the $600 a month in medication and gas goes on, and whether the sister three states away gets the same say as the sister doing the driving. A house that has to be sold does it too, so does a loan one of them cosigned in 2011 and is still paying on. The disagreement people describe as growing apart is usually a disagreement about labor and money that neither of them has said plainly.
Childhood closeness gets used once contact stops. The photographs come out, and the argument built from them is that two people who shared a bedroom for twelve years should be able to get past whatever this is, which uses a childhood bedroom as the reason an adult relationship should continue. The family repeating that argument is generally not the family doing the driving, and the woman it's aimed at is the one who already spent five years trying to make the adult relationship work.
Plenty of these relationships were never warm to begin with. One sister hit the other for a decade, or told the parents a story that got her punished for most of a year, and the family still remembers the two of them as close because they were in the same photographs. A childhood that looked fine from the hallway can be the hardest part for the sister who left to explain to anybody who wasn't in the house.
Remembering the good years does make a woman wonder whether the current distance is necessary, and wondering once is reasonable. What answers it is the last five years of behavior, the photographs are from 1994 and can't say anything about what a phone call in March is like, and a relationship that only produces requests for money isn't going to convert back into the one that existed when both of them were in middle school.
You were close with her at nine and it was real, it was also built by a house, a schedule, and two adults who made both of you show up at the same table every night. None of that exists now, so what's left is whatever the two of you do on purpose, and if what she does on purpose is call when she needs the $400 and go silent the rest of the year, then the person you're deciding about is the one on the phone in March.
