I typically sleep on the right side of the bed when you are looking at the headboard. However, once I (somewhat) jokingly told my wife that she needed to move to the right side b/c I was going to "bust a move [on her]" and "do my best work from the left side." We laughed, she moved, and I busted a move. Now when I come to bed and find her lying on the right side I've got a pretty good idea what she's got on her mind
