My home airport is KAVP, which has an active flight school. I heard the following communication between ATC and a student pilot.

Student:
"Ground, Cherokee 1234. Request staying in the pattern for practice touch-and-goes."

ATC:
"Report mid-field and intentions on each pass. Taxi to runway 4."

After the second touch-and-go, the following was heard:

Student:
"Cherokee 1234. Left-field downwind request touch-and-go, runway 4."

ATC:
"Left-field is baseball; mid-field is flying."
