How long has it been since the last time you had someone publicly jeer you?

Just got back from a hospital visit and while waiting for my ride to come pick me up had a bunch of High School age gang members come through and try to make fun of me for being bald while filming with their phones. I just ignored them and they moved on after several minutes, but hadn't been publicly jeered since Middle School prior.

Have you been publicly jeered before? If so, how long has it been since the last occasion?
