A brilliant idea...

If you know something is wrong/unhealthy/annoying to others, don't do it. Here is an example: I was in the express line at Target behind a woman with 3 small children. For some reason, she thought that the kids should pay for stuff with their own money. Unfortunately, they couldn't count money. So she has to tell them what to give the cashier. The injury to the insult is that she looked at me and mouthed "I'm sorry." Umm, next time how about you play grocery store with your kids at home. MMM-kay?
