This morning just as the sun was coming out I went out with the dog (she's determined to stick to the 7 am wake up). At the end of our driveway a half inflated, battered red mylar balloon with the number "6" taped to it was randomly bouncing around. It stayed there while I took the dog around the house and then back up to the front. It stayed there the whole time I was walking up to it. Then just as I reached down for it it jerked away from me a few feet like it was on a filament that someone was pulling.
The dog was all hackles raised and growling anyway and that didn't help. But it didn't do it again and I picked it up and chucked it in the trash.

I wasn't really all that awake at the time and now I'm resisting the urge to go out to the dumpster and take a peak inside to make sure it is actually there and I didn't just have a crazy walking dream thing.
