hw not done ! excuses needed ....

I am not under any circumstances going to advise you to lie to your teacher. YOu say you were "too busy". Too busy doing what? If it was something significantly imprtant such as a family emergency, natural disaster,etc then there should be no problem teling the truth. That is of course if it was a significant enough emergency. However...if it was anything other than that, you have no excuse and your teacher will likely not accept any excuse no matter how clever or elaborate it may be. If I do not go to work because I am "too busy", I won't have a job very long. You might as well start learning that now. At your age there is very little that is more important than your school work and the real world is much tougher onthings like that. If you ever decide you are "too busy" to go to work, they will likely just put someone else who isn't so busy in your place and you'll be out of a job. Suck it up, accept responsibility for putting your homework aside, deal with the consiquences and consider it a lesson.
