"No Mission Too Difficult, No Sacrifice Too Great—Duty First!" - The fighting first's motto.
Losing internet 9/7/2012 until i don't know when. See you starside folks.
Fada beo Halo 2!
This is probably similar to things already posted but,
if in all other games your GT is Chief077 :D!!!
if your armor always looks like chief's if it's possible
if 7 is your favorite number
if you don't actually know what the word "halo" means besides being a game
if when you get out of the house all you can think about is what your going to do in Halo when you get back
if you hear the soundtrack playing every time you get an adrenalin rush
if you run around outside with your friends armed with bb guns and yelling "FRAG OUT!"
if your walking behind someone and can't resist pretending to assassinate them with a knife
if you tell the traffic officer"I'm on Bungie.net and i promise to keep my sniper rifle off the streets
if you mount a machine gun on your car
if, instead of taking the stairs, you try to jump like a halo 3 spartan and forget that you really DO take fall damage in real life (i know that's already taken)
if when your mad at someone you offer to settle it with a Halo 3 slayer game
If you think Bungie has more luck than activision
(inside joke)
MOST of these are past experiences :)
