Thats very strange because i have seen that majority of Punjabis are lot more conservative than urdu speaking people, though , one can see all types in both communities. Is there any reason you have only met the aunties that don't have sharam? May be its not a Punjabi trait but the type of people you attarct or hang out with.
I attract? lol My family is more conservative, and we know them because so and so went to uni with my mom or dad, so we end up meeting them at dawats etc. But I just thought it was the group I saw that were like this, but then when punjabi girls themselves who attend the real punjabi parties, started saying all this stuff, I was like hmm okay I guess thats just how they are, or the ones in my area atleast. I've also met punjabi conservative families as well, but very few.
