Jane Higgins was walking down the high street when she bumped into an old friend. "Hello, I haven't seen or heard from you since graduation back in 1982!" said Jane, "what's happened to you?"
"Well, I got married in 1989 to somebody you wouldn't know. This is our son", said the friend who was holding hands with a little boy.
"Hello and what's your name?" said Jane to the boy.
"It's the same as Daddy's".
"Ah so it's Peter is it?" said Jane
How did Jane know?
I'll tell the source when somebody gives the correct answer
