I wasn't as lucky with the annonimity part of setting off alarms.
A warm sunny day with no breeze, just before school ended for the summer, I dropped by the highschool to give my boy a ride home.
Very quiet in the parking lot as I rolled in and the engine was just idling. I pulled up and stopped, turned the engine off and waited for my boy. A few minutes later, he came out, got in the car and belted up. I then fired the engine and bipped the throttle a couple of times to clear it out before I drove away.
Second bip did it. Must have been 15 car alarms going off all at the same time! My boy and I and all of the other students waiting for parents, got a real kick out of it.
Next day, the school principal called. You can guess the rest. No more throttle bipping please!
My boy was in seventh heaven at school next day with all of the attention he got from the other kids.
Too bad the principal had no sense of humor.......
