Red Light, Green Light....anybody?????

Morgan has started playing impromptu games of red light, green light. With nobody. She will suddenly yell 'green light' then turn around real quick, pause a moment, then turn and yell "red light'. She especially likes to do this at the end of the hallway, a good path for such a game, I guess.......... It took me a few times before I realized "A" what she saying and "B" what she was doing. Now, of course, I think it's just hilarious!
