Never shake a hand sitting down.

Number One

Protect who is behind you, and respect who is beside you.

Number Two

Never go after a girl your friend is already going after.

Never eat the last piece of something you didn't buy.

Never make the first offer in a negotiation.

Never insult the cooking when you are the guest.

Don't take out your phone during a conversation.

Listen, nod, and most of all make eye contact.

If you aren't invited, don't ask to go.

Dress well no matter what the occasion.

Don't take credit for work you didn't do.

Take blame, and give credit when due.

Proper grammar will get you far in life. Leave the foul language for the less educated.

Speak honestly. Say what you mean and mean what you say.

Show restraint in expressing anger, no matter what. Being angry is a waste of energy.
