That’s an a-hole thing to say. You’re personal comfort is more important than societal norms and acceptance. There are all kinds of people you meet in public? Would you say the same thing if it were my 94 year old grandmother that is talking nonsense because of her age?
The norm is or used to be that people have a right to expect not to be disturbed in their personal space. Maybe you remember the adage, "Children should be seen, not heard." I didn't make it up. I like kids; in their place. I certainly don't mind them in a restaurant as long as they are not disturbing people at other tables. I feel the same way about your grandmother; or the yuppie who wants to run the world from his cell phone; or myself even. (Does anyone here think I have a right to be drunk and start talking loudly about sexual fantasies at the table next to their kids?)
