I don't have a gun or a bat (I'm kind of scared making this known - are the criminals in my area smart enough to read as I "advertise" this?). But I do have a short sword, about three feet long.

Not too long ago we called the police to complain about loud noise, music, and fighting that was coming from next door and about fifteen minutes later some random guy came stumbling to the door, three sheets to the wind, demanding to know why we called the police and saying he was going to kick all of our...well, you get the idea!

Nothing came of it, but to make a long story short I, along with that sword, was waiting at the top of the steps for this idiot to make a move. I had a perfect bee-line to the middle of the kitchen the instant he would have barged through the back door. Had he broken in, he would have had more to worry about than a police report and a hangover in the morning!
