First....NO CRYING IN HOCKEY!!!
Don't ever be embarrassed if you can't do something or have a question. That is part of the learning process. We all had to learn, some just did it earlier than other. When you are practicing, don't every be afraid to fail or fall. You learn that way. As long as you are putting in a honest, hard effort you have nothing to be embarrassed about. If someone gives you crap because you asked a question, fell during a drilled or whiffed a shot they are the fools not you. Even the pros still make mistakes and they will tell you they are always learning something.
