That is so funny. I live out in the sticks and cell phone reception is very iffy. Best if used outside. Well, anyway, everytime my phone rings Pepper runs to the door, because he knows I will be going outside, on the porch to talk.
I use to have a little Maltese that would do something similar. I would come home from work after working the nite shift and get on the puter and check my emails etc. Well, when I shut down the puter and that little microsoft tune would play she would hit the bedroom flying. Cause she knew that when she heard that tune, it was time for bed.
