Employed as a dental nurse, I was on duty when Steve came for wisdom tooth extraction.
I took him into the examining room and made him comfortable in the reclining dental chair.
The dentist then injected a numbing agent around Steve's tooth, and left the room for a few minutes while the medication took hold.
When the dentist returned, Steve was standing next to a tray of dental equipment, "What are you doing by the surgical instruments?" asked the surprised dentist.
Focused on his task, Steve replied, "I'm taking out the ones I don't like."
