practice

You were a little overwhelmed and a whole lot nervous Miss Eva.  Daddy became an assistant coach to keep you on the field.  I think you might need a few more practices to warm up, but I really hope you start to enjoy it.  When I asked what your favorite part of soccer was you said, "the yummy juice at the end!"  You are willing to go back and try again, once I told you that the juice is standard protocol.
PS - Watching 4 year olds chase each other, coaches, and a few dozen balls around is hysterical.
