Some people have apps on their computers, so that when they're working for a long time without moving, the app comes up and forces them to take a break for a few minutes. I don't need an app. I have a Frank... When I'm trying to work, about every 45 minutes, he brings the toy to me so that we can have a toy break for a few minutes. Then when he's tired, which is about four throws, he won't come back to me. He jumps up on the bed. It's really funny, because Spike would continue to return over and over and over, sometimes for 30 minutes or more. I guess Frank is older and gets tired a little easier LOL. Here is an example. The video isn't wonderful because I'm holding the phone in one hand and trying to throw in the other, but you get the idea!
