Action Vs. Reaction

I have always lived by the cardinal rule that for every action there is a reaction. For example :

ACTION: Me using the term "ass crack of dawn" any and every chance I can get.

REACTION: While on the trails yesterday my mountain bike jumped up and hit me square on the ass crack to the point where I can barely walk today.

So needless to say, Action Vs Reaction, Karma, what goes around comes around and anything else that may apply here is alive and well in the Penley household. One should always watch what they say, be careful what they wish for and keep their ass cracks out of it !!!
