The alarm went beep beep beep.
Ya know, that beep that a smoke alarm does to warn you that its battery is low? Yup.
There's been one (or several?) going off for the past week or two. 24/7
I'm figuring that it's in one of the vacant apartments - there are several in the complex. (Anybody need a new apt? I can get credit for recommending tenants *weg*)
