When my two girls were in grade school, we were at the pet store picking up hamster supplies. When we were checking out, I noticed that the cashier, about high school age, seemed to be having a bad day. As I scooped up our supplies off the counter, I said cheerily, “Have a nice day!”
She glared at me as if I had two heads. As I turned to leave, I asked her, “If it was a choice, would you have a bad one?”
“NO!”, she said emphatically.
Leaving, I said over my shoulder, “Well, it’s a choice”, and out the door we went. To this day it always surprises me that neither of my daughters remembers the incident.
