The peaks are the least representative days available: the wedding, the crisis, the fortnight abroad. We assess our relationships by them anyway.
A truer measure is a Tuesday. Walking to the car park with a colleague you like. Two lines exchanged with your brother about nothing much. An evening in which nobody says anything memorable.
If your Tuesdays hold a few easy exchanges with people who know you, the relationships are working, whatever the photographs suggest about the rest of it.
