Don't be so hard on your self! Like someone else said wait til you talk to your teacher b4 you go out and buy another. She will understand that it wasn't intentional and only an accident. NEVER call your self a loser your not... things happen that we don't like but its just lessons to be learned, see next time you will make sure the bag is closed right We aren't suppose to be perfect and your teacher knows that. Once you talk to her you will see that you was hard on yourself for no reason So cheer up and think positive because it will be ok
