Well you always have to give the backup key to you'r neighbor !! imagine if a slasher comes in and kill me , that way my neighbor can lock him in and my death would be vain !!!!!!! ( what the hell am i saying )
Vain means pointless doesnt it? Soo... assuming you have all the windows and other doors locked... i suppose you could have been part of the killer's capture... =w=
Hmm there was a robber at my relative's place and they came back before the robber left so he/she broke a second floor window and probably used the tree to jump down~
