Things I don't get --
Who would wait almost 2 hours to eat at the Outback?
If you were in so much pain, why did you stick around to eat the free meal?
IF your whole weekend was ruined because of pain and you couldn't get out of bed, why did you not go to the Emergency Room? That is what it is for.
If you fell so hard and "I caught myself with my chin on the hardwood floor" Why do you not have facial/mouth injuries? It would seem to me that if the rest of you is injured that badly, you would have some broken or chipped teeth.

The Outback's lawyer should love your admission, in this letter, that you saw the water on the floor prior to your fall.
