Its because all they eat is fish! No that’s a lame joke its because bengali families are usually very close knit and strict and well us pakis have modernised quite a bit now!
Its ok for me the fiancee has just bought his own place and because were like friends w are both open to flaws in each others families and openly discuss them. We don’t have the sort of relationship where he will throw a tantrum at me over his mum or something like a lot do!
But what I can say is that the darn language is very different sigh
