Shear the Sheep...

I was talking with my 12 year old son yesterday about his day at school. He informed me that he had traded some worthless cards for some good ones in a game he plays with his friends. My first concern was that he might have engaged in some 'sharp' trading practices and taken advantage of his peers. Isn't that crazy? Good for him, I'm glad I didn't say anything. In a world where people do so many crazy things, send money to TV preachers, worship celebrities etc why would I want my son to hold these people harmless from their own foolishness? I need to teach him to shear the sheep closely when they self identify as sheep...save harmless your friends and the rest can take their chances...
