Falling in love...

My son said, 'Dad, when was the first time you fell in love?'

I said, 'I was 18. I walked into a bar and spotted the most gorgeous blonde I'd ever seen. Cupid fired his arrow the second I saw her.'

He said, 'So what happened?'

I said, 'Nothing.

Spoiler:

Unfortunately, the arrow missed and hit your Mother.'
