Maybe it's just me, but does anyone else get creeped out when someone knocks on your door unexpectedly? It's happened twice tonight. I never answer unless I'm expecting someone. I don't have a window to look out, and it's dark so the peep-hole is useless. I'm just not sure I feel safe opening the door to a stranger, not knowing who it is. It could be my neighbor, but I don't want to take that chance!
