Who is at My House?

So. I guess we have a visitor. We aren't sure what they want, we've tried talking to them and personally, I'm not getting an answer. I saw them walk by me last night, I thought it was Twohawks, but when I looked, there was nothing there. My oldest daughter has also seen it. Then, late last night something unplugged my computer. Now, this is quite a feat considering I don't have the kind of plug that can just be yanked from the wall. I have a flat-wall plug, with three prongs, the cord comes out from the plug sideways. It's hard to plug in, let alone unplug. My UPS started beeping around 11:30pm, after we were both in bed ~ and there are no children here this weekend. Something unplugged it though. Then Twohawks was awakened at 4:00 this morning by a loud thud. It doesn't seem to be malevolent, it just seems to be wanting our attention for some reason. Does anyone have any ideas?

...

It's me. Whooooooo!

Any more from this, Melissa?

Nope. I think it was my grandpa letting me know something was coming down the pike.

Don'tcha kinda wish he'd a just written you a letter?

Has there been any more visitors ?
