I didn't answer it when the call came in, but they called once at 11 PM then twice at 8AM. The number on the caller ID had too many digits to be a real number (919-689-652289). They left a message after not answering, which i couldn't understand much of other than something about a window, and knocking first. may have just been a wrong number. but when i called it back i left off the last 2 digits and it said the number was disconnected. Oh and its a NC number.
