Ok, your doing math homework due tomorrow your pencil breaks, あなた have no pencil sharpener, no other pencils in your house, and あなた can't use pen. What do あなた do?
Get a short, sharp ナイフ and cut away the shavings to allow the lead to come through. Just make sure あなた sharpen in the direction away from you. あなた don't want to end up with a ナイフ sticking out of your stomach.
Wait until the morning until あなた get to school, borrow a pencil from a friend and ( if あなた stink at math like myself) クリスマス 木, ツリー the thing. Or! bare with me on this.... dont do it. I prefer the later.
What I always do, Wait until the 次 morning, freak out, and then do it at school, Oh wait... Our Math teacher doesn't give us homework...................................
This ALWAYS happens!! I would either use pen anyway, use a ナイフ to sharpen it, go out and buy one, but what i usually do is use the lead bit that broke, または wait until the 次 日 to copy off someone. But copying off someone can be a problem because everyonw thinks the same thing, so they come to school hoping to copy off me! So in the end none of us do it:)
