So after all that worry about what I was going to wear 2 things happened.
1- She called and asked if we could go take our kids on a walk/bike ride on our walking trail. So I ended up wearing a jacket anyway.
2- As I was getting Max to lock him up in his kennel, he decided I was really frightening and promptly pee'd all over my arm as I picked him up. He's never done that before. So I ended up in wearing a long sleeved white t-shirt.
