By all means go for it , if you think that they will be ok with it. If you think that it can create problems for you then better safe than sorry. It is not war of wits. On a personal note I would try to find out beforehand if they would be ok with my lifestyle , my belief system and my family values before finalizaing a rishta. In my own wedding we had all kinds of parties and rasoomat and lots of halla gulla , lots of fun.
They're a little more conservative than we are, thats for sure. So far, they've never stopped me from doing anything or said no to me. This is the only issue they have a problem with. Another thing is, they only visit the US every few months. They dont live here because they have a very comfortable life in Pak, Mashallah.
