It must have been in high school because it was at the drycleaner's dropping something off (for my parents evidently) and Lord knows that I have not been to the drycleaner's in 20+ years!
I vaguely remember getting out of the car to take the drycleaning in and leaving the car running and somehow it locking.
No cell phones then so I must have called my parents from the drycleaners and waited for them to arrive.
I did a lot of dumb driving-related stuff in high school.
