Oh boy.
I'm on thin ice commenting on this kind of stuff since I'm not desi. Thankfully I haven't seen many of these characteristics in my husband's family and I'm confident we won't be implementing them in our parenting!
The one thing that does get on my nerves, though, is the tendency in many desi families to let little kids run around at night until they just drop from exhaustion. I'm a huge fan of helping kids establish a nap schedule and a decent regular wind-down routine and bed time----studies show it really pays off in terms of the child's concentration and performance in school, and having a reasonable bedtime leaves time for the parents to have some nightly quality time together and not get into the rut of just being mom and dad 24/7.
