The song you pulled a face at

You grimaced once at a song on the radio, something with a saxophone and a great deal of ambition. Weeks later, on a long drive, he reaches for the dial before the intro is done and switches the station without a word.
He treats your opinions as data. Not every preference needs a discussion, and some of them just need a hand on a dial. It is a small, dry brand of devotion, and it comes with an entirely straight face.
The thing you swore you would never do again

You told him you were finished with big birthday dinners after the last catastrophe. So on your birthday there is no restaurant, no surprise guests, no balloons. A small table, four people and a cake you did not ask for but would have picked.
He listened to the opt-out as carefully as he listened to everything else. Plenty of people remember what you like. Far fewer remember what you refuse, and fewer still honour it when ignoring it would have been easier.
He follows through on what he said he would do

Last month he mentioned he would take a look at the noise in your car. Today it is quiet and there is an invoice for a part tucked in your glovebox. He raises it as though it had happened to somebody else.
This is where all the other memories were headed. Remembering is cheap; following through is where the cost turns up. A quiet man who remembers and then actually does the thing has told you more than any of the sentences he chose to leave out.
