I talk to my PC, to my phone, to my food, I say "excuse me to our pets" etc etc etc...
I think it's personification and imagination at it's best.
It doesn't freak me out in the least, b/c I've done it for as long as I can remember, and always credited it to my active imagination... I do it ALOT, with or without company, and if someone thinks it's weird, then boohoo I'm weird,

build a effing bridge!
Guess all I really wanted to say, was, "I feel ya"...
