[usr] I keep hearing noises out my window and I'm home alone. It's very concerning. [sys] Should you call the police or something?  I hate being home alone for this exact reason. [usr] I don't know, it's just scratching so maybe it's just a raccoon. [qst] ask me for further details [bhv] [None]
Or a cat maybe?  Maybe you should look into installing those motion flood lights or something so that you feel safer when you are home alone.
