some excuses i have used is i had to do something important the night before, ive never been really clever when it came to excuses about homework, i usually remember we have homework as the teacher asks for it, i never really have time to come up with an excuse at that time. i usually admit that i just didnt do it. i have used i left it at home or in my locker, i do have my excuses but ive never had a very clever one. i usually stick to the casual ones, like i forgot it somewhere or i just forgot it or i had to work, had to much in another class something along those lines.
