how scary for you honey, I think I would react in a similar way to how you did though and I understand that security feeling, I'm not usually too bad but I have an over active imagination (not helped by a dog who feels it is his duty to bark 5 times as much as usual when dad's away because daddy told him he was in charge until he gets home)I've been known to creep around the house at night and check all the doors and windows just to reassure myself (I also have a really silly habit of watching shows like medium and ghost whisperer while DH is at work and scaring myself silly with things that go bump in the night just before bed time)
I hope you have some good neighbours as well.
the man across the street once told DH not to worry about me when he's working away because he keeps a shotgun under his bed and will come running at the slightest sign of trouble, and I really can't imagine why this wasn't all that reassuring to me!!!!!!.
I know he meant well.
For the most part our neighbours are OK and our house is situated in a position that unless they come through the front door it would be hard for anyone to sneak in this still doesn't stop me imagining the worst all the time LOL I'm such a sook.
