The mouse got knocked on to the floor and received brain damage. It would no longer move the arrow around on the computer screen, we were having to use the little green button in the middle of the keyboard. After I wined and complained, Don got hold of a tiny Phillips screw driver and did brain surgery on the little rodent. The operation was a success!!! Now that the mouse is again pushing the arrow around and I don't have to use that little #%^&*#%^ green button, I'll catch up on my emails.
