You know more than you think! 11.5 points (.5 for the nickname).
#2 I don’t think I ever mentioned nicknames but my mother does call me Sar and one of my friends calls me Sarita.
#5 pretty much depends on the day of the week but it can go both ways.
#8 close with the k-pop, but it’s more jpop
#9 I’m actually Polish (with some German) but I was born in the US.
ps, I am sad because you were totally spot on with my age, dammit
