Privacy

This girl in a Thai restaurant today was saying, loud enough for everyone to hear her, how she couldn't stand some other girl who wouldn't tell her her age, for that reason, and how she "can always find out. And she said, find out if you want but I'm not going to tell you." I mean, why is it so important for her to know this girl, someone who is a stranger,'s age? I think it's rude to ask age to a woman, or that's what I was taught. If someone wants to keep something private, a person should respect those wishes. Why does she want to be a voyeur into this person's life? People like that really do scare me......
