Thumbs Down, Change Behavior

Why can't parenting work like Pandora?  If I don't like a particular song, I click the thumbs down icon and look forward to the next song.  Delightful.  I tried it today with Finn.  Medium boy was doing something I didn't like; I held up my thumb, pointed down and waited for him to move on to a new behavior.  Um, no, it didn't work, but I'll keep trying.
