Yep, I had to come up with a list.  Did I miss anything? 

1. Thou shall not bring large shampoo bottles through security.  It’s almost 2012 people, you should know better. 
2. Thou shall not board until your designated seating is called. You know who you are.
3. Thou shall not place your luggage 10 rows ahead of your seat. Not cool.
4. Thou shall place your carry-on in wheels first.  It it doesn’t fit, it’s not a carry-on.  Either check it or get new luggage.
5. Thou shall not raise the armrest.  I don’t know you, that’s awkward.
6. Thou shall make attempts to discipline your children.  I’m not asking for silence, but please put in some effort.  I’ve listened to children scream for hours without the adult saying anything.
7. Thou shall not  try to use the restroom during meals. Also uncool…I am not an airplane acrobat.
8. Thou shall not try to run up the aisle cutting everyone when de-boarding.  See #2.
9. Thou shall not yell at your stewart(ess).  It’s not their fault the flight was delayed or the food is terrible. 
10. Thou shall not talk my ear off when I’m trying to sleep.  If I have my headphones on and my eyes closed, it’s a good sign I don’t want to hear about your cat.
