Do you mean if you come with an elderly lady, we assume she is your mother and ask you to produce a birth certificate???? Well boy grow up. A family could mean any relation and the family day restriction only intends to portray a message to these nasty wanderers that one has to give privacy and space to even people who need time with each other. I am sure you will agree again that we live in a foreign country, no rule for that matter is just for expatriates no matter you live here or there. And moreso its true rules apply only to us whilst the locals are free to do anything. But we must try to protect our dignity and show that we are far more better than others in our beliefs, values and respect for one another.
