Sleeveless

A few days ago Jack, aged 2, soaked his shirt sleeves playing at the sink. So, I did what any mother does and changed his shirt. All I had that was ironed was a short-sleeved one so, as it's cold, I put a cardigan on over the top.
Being Jack, he soon pulled the cardigan off and got on with playing.
A little later we were getting ready to go out and I told everyone to get their coats.
Jack suddenly let a shriek out of him and announced, "Oh no, my sleeves are rubbed out!"
He had earlier watched his big sister rubbing out a mistake in her homework book!
