Maybe, it wasn’t, maybe there was really someone in the house.
My husband never takes these things seriously, so he just didn’t do anything when he heard it.
The IT guy at his office told us that we had 5 people logging onto our computer every single time we got on the internet, but he couldn’t tell who it was.
I asked a techie once about that and he said they could trace them.
A couple of months ago, I got satellite internet. It is the only thing available out here except dial-up.
The device which receives the signal and then routes it to my computer has little blue lights which show when data is being sent or received. It is actually right beside my bed.
I have noticed that often in the middle of the night when my computers are turned off, that I sometimes see both the send and receive lights blink for a few seconds.
Oh, crap! That's soooo creepy! :-(
