I was sitting on my bed looking intently at Orbitz to find hotels for an upcoming trip. I had the cursor next to the Firefox window.
Penwiper walked up, pressed her paw on the trackpad, and once the window had receded (bringing up my mail window), walked off. She did not walk on the computer, merely hit the trackpad to replace the window I was working with. I think she's annoyed that I was not paying attention to her.
Next thing you know, she'll have her own Facebook account.
