> but culturally I care less about American sports and music
Culturally I do not even understand this fascination with sports; we watch football (soccer) when there is some worldcup on and our country is playing but besides that the whole highschool quarterback and rooting for your teams all seems like wasted time to me. That might be cultural.
But I always turned that into a strength when making friends. If most people do something like watch sports or listen to music I do not like, I find the people that do not; those will be a niche. But I do not seek them out in obvious places with all likeminded people; when I go to AUS or US (and certainly when I was younger and looking for (girl)friends more) I go to sports bars and or clubs (where they will play music I do not like); in those places there will be 1-2 people like me that were dragged along or went along with their friends and who will be bored. Those end up talking with me and sometimes become good friends (two American ex girlfriends and many good friends, some I still do business with like that).
