Why don't you have a boyfriend?

If he insist, be direct and tell him "none of your business".

Tell him you just haven't yet met Mr. I Guess You'll Do.

He has no business to poke his nose into your personal affairs. These kinds of guys should be totally ignored.

Some people like gossip. I can understand how annoyed you felt to it since it is your privacy. It is nobody's business.

Some people don't know that some things are none of their business.

I don't want to be asked too why I don't have a boyfriend. It's my fault I'm not a flirt when I was younger so didn't find a love life

If the one who told you that is a girl that already has, then really quite an arrogance. If it is a man who's also a single, maybe he has some plan on courting you. If a man with partner already, seems building a peer pressure. If it is your friend, then maybe just concern?

Some people don't respect others boundaries.

That wasn’t appropriate. Good that you ignored him

Say, "What is it to you?" Tell him that you aren't interested in his private life, either. So he should leave you alone. No need to be friendly to him.

Oh...funny and crazy people. Not having a boy friend does not mean not having a love life. In India, it is only a negative point to have a boy friend. Of course, the trend is changing now. At the same time, people are not viewing of not having any boy friend as a stigma. Moreover, there is an open verbal attack and criticism of parents allowing their children to have boy friends.

Yes some people speak non sense.

Iam not clear with the guy intention.but the fact is the more you feel offended the more it will disturb you.

It would have been great if he had asked your age too in front of everyone :)
