Ask for directions quick
This is easily done but a real rookie mistake to make. In your rush to get out of the situation you are in - never forget to ask where you are!
Whether's it's him, his room mates, his friends, maybe even his mom, 'Where am I?' will help make sure your walk of shame won't turn into a trek of trauma as you take a wrong turn at the end of the road. Better yet check out the address on one of the letters in the hallway.
This will also lead back to a previous point - check yourself in the mirror. People are going to be less inclined to give you directions if you look and smell like something that appeared from the swamp - sad but true.
