Henry walked down the street and bumped into his old friend from university.
"I haven't seen you for ages! I've married someone you wouldn't know." said the young friend . "This is our daughter!"
"And what's your name, girl?" Henry asked the little girl who was holding his friend's hand.
"It's the same as my mummy!" Said the girl.
"Oh so it's Teagan, is it?" Henry asked.
He was right! How did he know the girl's name?
The old friend of Henry’s was the mother of the little girl! Most people would assume that Teagan Senior (the friend) was a man because Henry was a man! So Henry just said the name of his friend!
