yes! I find myself watching the behaviour of other kids at the park, malls, and so on. I told kids to stop climbing the trees at the park (these are baby trees and half of the branches have been torn off by kids trying to climb them) I told the kids (nope, I didn't know them) to get down, while their nannies sat on the grass playing with their iphones. I have shaken my finger (the no no gesture) at kids misbehaving in public places (without even thinking about the parents reaction). I did manage to restrain myself at the mall where a five year old boy was repeatedly shoving his mom over and over again while she tried to have a conversation on the phone (i actually had to leave the area because i found it so ridiculous that the mom just carried on talking on the phone)
