THE WALKING DEAD

You are laying in a hospital bed not knowing how you got there or how long you have been there but you do know that you have been shot, and notice the odd silence in the room you yell to the nurse for assitance but know one replys so you yell again but still no reply. you look around the room and notice that there is a hospital bed pinned up against the door not knowing you decide to get up and inspect so you un plug your iv bag and proceed to get out of bed. As you are walking towards the door you notice a window in the room and decide to look out but notice there is know one in the street so you proceed to walk to the door. When you get to the door you remove the hospital bed and you open the door, straight away you notice that there is still no sound coming from out side your room, as you walk in to the hospital hall way you notice somthing banging on the door. so do you a) keep walking? or b) open the door?
