This reminds me of many years ago when I was still at school. I had a gig playing guitar at a local cafe. One day a woman came in with a young girl of about 4 or 5 years old, she looked like she was probably her grandmother.
The little girl started dancing to my music and her grandmother told her off and said "Stop it, you can't do that in here!"
The girl replied "But I can't help it".
One of my memorable moments as a musician.
