Oh, um I have (and had) a person who randomly runs a lot and they don't like running or anything it's on VF.

For no reason normally when they are "Working on career", and other things in the office.
LOL! I remember when I had a 55 yr old do it

Why are they doing it?
Random: do you hear the funny sounds they make when they are "Studying in the kitchen". I like to wait for them to do it even when I'm in a hurry!
