My wife Maria has the occasional senior moment. The other day, she was working in our local Kirkwood Hospice shop.

A young lad dropped a sweet wrapper on the floor and walked out. She picked it up and put it in the bin.

An hour later, two lads aged about 12 came in and asked: “Have you got an M&M wrapper?”

Perhaps, she thought, there was a competition number on it. She rummaged in the waste bin and handed over the wrapper she had earlier picked up.

The lads looked at her as if she were barmy.

“No,” one said. “Eminem. Rapper. Music.”

The lads left and a lady customer collapsed on the floor laughing.

“I should have known,” my wife explained. “It was a Snickers wrapper, anyway.”
