Maybe because Nepalis like to compare themselves with each other. Happens way too much. Falana le ghar kinyo re, dhiskana le yo business gardaicha re, yesle yetti kamaucha re, tyesle tyetti padheko cha re.... yadda yadda yadda. I guess this happens in all ethnic communities, but for us Nepalis, seems like it happens more with us. I love hanging out with Nepalis, but this compare-garne-bani chahi patakkai man pardaina. This could be one of the reasons why it is what it is in Bay Area.
