Thats a real bummer. But during times like those you have no choice but to be optimistic, and it seems you are in pretty good spirits considering. Thats good becuase theres no reason to get down about something you cant change now. Think of it this way, maybe it happened for a reason. Maybe if you wouldve gone to the game you wouldve got hurt even worse somehow. Maybe someone was watchin out for you.
And also remember at least you are lucky enough to be able to run around the yard and play with your kids. Your ankle will heal. God Bless. And Go Big Red!!!
