Right now one of my NPCs in an ongoing RP who makes occasional cameos as a point of view character shares a lot of traits with me. 

-We're both Vietnamese by descent (although I'm only half; her parents are both Vietnamese) 
-We have the same body type (short n thick) 
-We both hate sexism even if we are guilty of the double standard of being boy-crazy and objectifying men a lil bit 
-We both are markedly unambiguous and happy to work a blue collar job and make ends meet despite a history of parental pressure to do better 

I didn't intend to make her a self insert, but the more scenes I write for her the more she turns into someone I'd like to have a beer with.
