You were raised better than that, weren't you?

Often I have to tell my children that it's not OK to do something, which is fine because they are only 10. For example, the other day I had to tell them it's not OK to:

Argue with Mommy just because you're tired.

Argue with Mommy over sneakers, healthy snacks and/or early bedtimes.

Argue with Mommy over everything under the sun.

Argue with Mommy for two straight hours and then expect to swim, have fun or live.

You get my point.

What I find truly amazing is how many times I want to say, "That's not OK" to my fellow grownups. I often feel as though I'm in a high school cafeteria, except high school kids have better manners.

I have to stop myself from committing random acts of scolding, wondering out loud, "Who raised you?"

People over the age of 30, 40 or 50 should know better, but often they don't. So for all those middle-aged kids out there, with manners that would mortify their mothers, please be advised that it's not OK to ...

Clean your ears with car keys.

Leave the bathroom in disarray. Come on, people. Flush.

Sniff and swallow what should seriously be blown into a tissue.

Clip your nails as you walk through the office.

Manhandle my tofu and flax seed in the community fridge when you obviously don't do healthy.

Burp loudly and then attempt to high-five everyone in the room.

Touch me or my hair and wink. It wasn't cute in college and it isn't cute now.

Sweat all over the exercise equipment. Those towels are there for a reason.

Deposit whatever is under your nails onto your sleeves or pants.

Wear tight turtlenecks when you're male, near 70, and easily a C cup.

Pick your teeth outside the bathroom.

Chew with your mouth open.

Play with the hair growing out of your ears.

Audibly digest anything.

Refer to women as broads, especially if you're under the age of 80.

Rub a pregnant woman's belly. Ever.

Shove children aside for a better view of the parade.

Blow your nose in a restaurant.

Throw cigarettes on the ground.

Ask others to "smell this." If the milk or cheese is bad, throw it away, otherwise you are risking a lawsuit.

Interrupt people with whom you disagree. Just because you're loud, doesn't mean you're right.

Complain about aches and pains; no one cares about your groin injury.

Invade my personal space after your onion and garlic lunch.

Spit in a garbage can or on a baseball field. We can see you, you know.

Touch any part of your body while discussing third-quarter earnings or yearly reviews.

Or this list.
