My husband would do the same thing. It's one of those things you can't really explain. LOL
Getting mildly serious for a second, I have heard this theory that people who are on a message board, in a virtual meeting room, on a conference call, or that sort of thing, they are sort of sharing the same space on a quantum level. IOW, they are mentally and energetically sharing the same space even if they aren't physically close. Like I said, it's just a theory (not mine), but it certainly feels true on FR live threads such as this. Like everyone is just in the next room or just out of the line of sight.
Okay, back to silliness!
It's called Quantum Physics. Now don't go crazy when I tell you that a "partical" can be here and there at the same time in Quantum world. And a partical seems to know what the other particals are not only doing, but thinking.
I definitely believe that's true.
