Re: How to react ?
I think you should be kind towards such kids and their parents. Allah maaf karay - that could be any of our kids.
I am not saying to eat the naan or let the child do whatever they want or disrupt the party but at the same time - maybe give them a smile - find a child a toy or something to keep him pre-occupied while the dinner goes on.
Imagine those parents probably never get a break. They constantly have to be on the lookout for if their son or daughter behaves or not.
I feel for the parents because the kids doesn't know any better. I would personally maybe let the child fiddle with my food and while his parent ate and then eat later. (just a thought)
i don't ask the parents what happened - I think it's too much of an intimate topic.
