The most dangerous game.

Simon has created a game that involves him running at top speed around the corner and coming to a screeching halt before he falls down the steps.  I think he wins the game by either stopping in time or giving me a heart attack.
This is why he can't be left to his own devices for even the shortest amount of time.
I've been unwittingly volunteered as the designated catcher and hugger for this special little sport.
I'm guessing that playing tag with River has lost some of its excitement and he's resorted to this.  I told him he needs to come up with a better (safer) game.  He just nose-bonked me, so I'm hoping that's a "yes".
