Sometimes it takes getting your ribs crushed from a tackle by a fat guy to open your eyes to reality...if he doesn't have enough sense after that to grow up, perhaps he needs an MRI on his brain as well.
I'm just joking with you...I don't mean to make fun of what could have been a very bad situation for him, and I'm glad he wasn't injured more seriously.
Let him live his life...you keep living yours. Stay on the high road.
