No harm, no foul. Kids can yell whatever they want at me and I let it slide. I don't feel the need to take action until someone attempts to hurt me.
My favourite is riding past the skate/bike park, because I get a few BMXer kids that want to race (which I lose intentionally) or challenge me to wheelie contests (which I lose because I'm not as good as them.) They laugh at the 'old' guy, I laugh and tell them "I'm stopping at the bar on my way home and having a beer, wanna come? Oh yeah... you can't." And we go our separate ways.
Throwin' the horns is always a great manouver. I'll have to remember to toss one of those in there with my banter amongst the skatepark kids.
