People, it's only a fugin bike - no reason to go postal on some little kids. If a kid touches my bike, obviously they are smitten with it, and I dont mind taking a minute to show em the bike and making a good impression on a possible future rider. Sure, let mom or dad know the thing aint cheap, but do it in a way that doesnt esculate a situation.
Now, if they cause damage to the bike, well than I guess I deal with the parrents on that issue. If mom & dad are tards, and damage is done than I make a call to 911 or get a DL and report to insurance. No sense in getting all worked up on material things - life is too short.
Now, if my fiance's kids run up to a bike and like the 4 year old boy always says "Bike-A-Busa" with a big smile on his face (because this kid is just completley in Aww of any bike that looks like my Busa), and some @ss munch decides to threaten the kid or me, I take that as fear for my kid's safety and mine and have no problem resorting to a quick verbal lashing about using some sort of threatening tone in front of the kids. And if dude wants to pull Mr. Tuff guy, red faced and fist's a flying sorta thing, I take no issue with doing what needs to be done if I have no other option. Just remeber a motorcycle doesnt make you a bad @ss and people get real defensive around their kids, & you might find yourself doing a faceplant in the parking lot.
Just remember, kids are frickin kids. Yah, kids do stupid stuff....thats why they are kids. Hate to see what some of you would do if a special-ed person got on your bike and made vroom-vroom noises...ya gonna kick the tard's @ss...please. I dont care if my comments arnt "PC", it only a bike.
