This incident happened about 3 or 4 years ago; out Grandkids were like four years old, and we kept them all day every day, except at night. This day had been particularly trying, and I woke up in the middle of the night, about 2 or 3 am. Unable to sleep, I went into Sharn Jean's sewing room, which also serves as the computer room. It was a particularly quiet night; the AC was not running, nor was the refrigerator or anything that made a noise, except the old Regulator clock that has been above the fireplace for the last 40 years or so.
I was piddling around on the computer, studying Einstein's theory of Relativity or the career of Marilyn Monroe, I don't recall which at the moment, when I thought I heard a muffled voice coming from the living room. I wasn't particularly scared; we live in a rural area, and at that time had two dogs that were pretty good at keeping us informed when someone was about; besides, if someone had broken in, I figured I would have heard it...but I was at a loss to explain the voices; and even though I wasn't scared, I was something close to it.
I got up from the computer, walked very slowly down the hall and then crept very cautiously into the living room. As my eyes slowly adjusted to the dark, I couldn't see anyone by the nightlight, nor could I see anything that looked out of place. I stood there for a minute, looking around, when I saw a dim blinking light, coming from the big laundry basket that we used as a toy box...and then came the voice loud and clear from the toybox: "To Infinity and beyond!!!"
