My girlfriend will look at things eg. Colours, items, clothes, food etc and point out all the things she likes. For me those things just exist and I don’t have much of an opinion on them. Like theres 100 paint colours them but they’re all fine, how am I meant to know whether any are better than the others.
I am also not known to get visually excited about things, I got a skydive for my 30 birthday and I think everyone was disappointed with my reaction even though inside I was very excited to do it.
I’ve noticed that natural facial expressions are critical for social interaction. I sometimes panic in awkward situations which leads to by classic blank look which is intercepted as not caring or being selfish.
