curl up in a corner and cry because i'd probably get killed
after that i'd hoard whatever i could get my hands on and head to the apartments about a mile down the road from me.
in my head i'd realize i wouldn't have to worry about other people on the road and think about taking a car, filling it with food and supplies, and go track down my friends if they're still alive. then i'd realize there would be a lot of traffic jams and zombie to worry about and resume crying in a corner.
