I've read a fiction book she likes, I've listened to music because she likes it, I sang because she used to sing professionally in the past, I began playing the keyboard because she's into music and I thought I should do it too. Because I've been embarrassed for not liking neither music nor movies for a long time before therapy. I think it makes me extremely boring. When my T said she's into music I decided to force myself /try it, because it seems less boring and a smaller waste of time than movies. So I have something for small talk with people :-D once I ate an ice-cream when she mentioned she'd eaten it recently.
