Shawn:  “Gran J, if Chris Davis broke the Orioles record of 50 for most home runs in a season what is the record for all teams?”
Me:  “Barry Bonds has it but I don’t know how many he hit.  For me the record will always be Roger Maris at 61.”
Shawn:  “Why’s that?”
Me:  “Because Bonds cheated.”
Shawn:  “How’d he cheat?”
Me:  “He used drugs.”
Shawn:  “How did the drugs help him hit home runs?”
Me:  “It made him stronger.”
Shawn: “What’s wrong with that?”
Me:  “It wasn’t right.”
Shawn: “Why not?”
Me:  “Bus will be here soon, go get your stuff.”
