Sam over heard what he could. These people seemed safe but as for how he would get in was another matter. Somewhere high would be the best place, as those things could not follow him in, but climbing was hard for someone of his size, he had little choice in the matter other than being shot by the people within from breaking down one of the outer doors so it looked like he had to be polite... 

Walking around to the entrance that lead out from the kitchen Sam knew that someone was there so he gently knocked on the door, hoping that whoever it was would get their attention caught "Come on.. Hello? Please open the door." He said impatiently, not really comfortable around where dead people were buried, more so now the dead seemed to get up for a stroll and light snack.
