Funny story

A guy goes to the supermarket and notices an attractive woman waving at him.
She says hello.
He’s rather taken aback because he can’t place where he knows her from.
So he says, do you know me?
To which she replies,” I think you are the father of one of my kids.”
Now his mind travels back to the time he has been unfaithful to his wife and says “My God, are you the person I had something to do with and I forgot to collect your number 5years ago or the lady I was too drunk to ask for her name when I was on a trip to Abuja 3years ago???
She looks into his eyes and says calmly, No. "I am your son’s school teacher"…
