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.
Once I saw a categorisation I liked. There are three kinds of people: those who know what they want or like, those who know what they don’t like and the confused ones.
In other words, it’s totally fine even for neurotypicals not too know if something is better than the other, especially when it comes to subjective reactions based on subconscious or feelings.
