On a trip to Glasgow I was approached in a shop by an exited old lady,
"It's YOU isn't it?"
"Er...well, yes, it IS me"
"Aye! I knew it was you as soon as I saw You!" and turning to her friends looking in the shop window, shouts loudly "I TOLD YOU IT WAS HIM!"
I was a little worried that she might want MY autograph as I wasn't too sure who "I" was, but she seemed pleased enough to have spotted me and left me there, none the wiser.
