All the friends I've ever had were Americans except for a couple.
One was British and he acted basically like the average American + tea, Football(soccer) and rugby.
Then I was friends with a Chinese gold farmer for a while(couple months) when lineage 2 had just been out for awhile. He was botting for gold most of the time and would piss my brother off and my brother would kill him, eventually the three of us started talking even tho he didn't know much English and we became friends while he was farming gold to make money while he was in college cause gold farming was like 5 times more money than working in a factory and easier. After my pet or something died or broke accidentally(which took like several months to get) I got pissed and quit the game so I never saw him again. And again he acted like the average american except for the fact we couldn't really understand each others jokes most of the time.
