New Year's Resolutions in the Classroom

I arrived early to pick up my class at Health today.  As I stood at the door I overheard,

“My New Year’s Resolutions are to get better at guitar and to not fight with my sister.”

I stepped in and the Health teacher acknowledged me. “You know Natalie, your sister Lisa had the same resolution two years ago when SHE was my student.”

Natalie looked at me, puzzled.

“We didn’t have our guitar then.”
