My student's mother, while my student is in the bathroom: "Heads up, I hear strep throat is going around again..."

Student, returning from the bathroom, has a special announcement: "Mommmmmmmmm, my throat is sore!" Then she sneezed on her violin and handed it to me to tune up.

I made a mental list of all the preventative remedies I was going to take when I got home but instead I had a big glass of sherry.
