Conversation over the hand-dryers

Stranger:- So are you staying here?

Me:- Yes

Stranger:- How long are you staying for?

Me:- We are going home tomorrow

Stranger:- Do you have children?

Me:- Yes 2 teenagers. 13 and 14

Stranger:- Not yours?

Me:- Yes they are

Stranger:- No, you don't look old enough to have teenagers. How old are you?

Me:- *whispers* 37

Stranger:- You are kidding me, You only look about 20.

THANK YOU
