Humm let me think.. 1.) people or kids with no manners. I just raise a eyebrow at my kids and they know ,I dont care who it is my kids better darn well say thank "you" and "please ".
2.) people who stare or make comments about people who use handicap parking. You can't always see the illness so just keep your comments to yourself. Worst ever was a women and child, child asks mom " why is she in a handicap spot shes not handicap ? "Mothers reply "well she must be one of those handicap in the head " This is what we teach children , if you don't see it , it isn't there. Heaven forbid if you suffer from a invisible illness.
3.) people who let dogs go poop on someone elses lawn and don't use a poop bag.
4.) people who dont take time to train their dogs then wonder why they don't behave.
5.) people invading personal space then Bump into you.
