We Know Better

Yesterday I decided to pay attention to stuff that people should do but don't do. Among my findings:

Everbody, Again: Don't drive and talk on your cell phone. Period. No excuses.
Everybody, Again: Don't even answer your cell phone when enjoying conversation with friends. Emergency phone calls excepted.
Everybody: Flush. Then wash your hands. This applies mainly to middle school boys.
Parents: Check your children's Internet "history" often.
Myself: Eat less. Eat better. Exercise more. Or better yet, start exercising, period.
Everybody: Say "please" and "thank you" when dealing with retail clerks. They're not servants. They're people.
Parents: Talk to and with your children. Do NOT condescend to them. They're growing up. They'll make mistakes.
Grown-ups: Strive for excellence in your chosen field. Don't settle for less than your best...because when you talk about how you cut some corners and others hear it, they lose respect for you.
Drivers: Park with consideration of others. Don't take up two places, look at it, and then shrug your shoulders and go into the store.
Everybody: Don't yell at anyone. Ever. For any reason. Especially in local fast-food places, where the teenage clerk showed more restraint than you deserved and frankly, he could've pounded you. He should've.
Drivers: If you know you have a turn or an exit coming up, get over sooner than you do.
Kids: Don't put your parents in a position to say things like, "I'll smack that look right off your face." They shouldn't have said it, but you shouldn't have done it.
Everybody: Don't say things to others hoping they'll communicate what you said to the person you're talking about. While I appreciate your input, I don't really have any influence in some areas. It'll mean more if you say it directly to that person. Trust me on that.
Myself: Talking to the television screen will not help your team score.

And that's just the stuff I wrote down. What else do we see know better that we do anyway?
