That's because you're just your typical paranoid cracker. lol
I've had a knife and gun to me more than once, been cut, been shot, had my house broken into with me in it, car stolen, jumped by mulitiple people - the list goes on and on. Granted, I've been that person some people may be afraid of, too, but I could still never react like some of you. I don't live my life in fear. Being that jumpy will only get you and/or someone else hurt for no good reason. Maybe she saw your light on? Maybe she knows you stay up late. Oh holy shit!! She's your fuckin neighbor. Being she's not a paranoid, gun toting, crazy (lol, j/k on the last one), maybe she thought she was just trying to be a friendly neighbor. My roomate left the keys outside with my housekeys and car keys in some apt in Santa Ana and a few days later someone tried to come into my house (seperate from the time someone else actually broke in) and then a couple days later, my car was stolen with those same keys. Granted, she should've couldv'e waited, but wouldn't you want to know where your keys were in the before school, work or whatever in the morning?
Long story short, get some wet naps for the sand and chill the hell out. lol
