99% of the time we dont know what the hell is in the packages.. and the bosses tell us to hurry up and get the truck down.. so we have to move fast and when we are moving fast we might pick up a box that has somethin like a solo x in it.. and it shifts on us and it falls out out hand.. or we might be mad or having a bad day and we might throw the box... or it might be in the back of a long truck and the belt would run out and we have to throw the packages to someone.. that person might be a girl or just a weak guy and drop ya box..
