ok!
time to stop it Clinte.
homework can wait seriously it can
what you wanna do right now is go wash your arm in some nice warm water in the sink with some soft soapy sh.t and bandage up ok!....wrap your arm up in fresh white anything and sit down in the quiet and hold your poor arm close to you and hug it mate....ok!
your arm has always been there for you....so now you gotta be there for it..
