How to tell your teacher i didn't do my homework?

"Teacher, I didn't do my homework. I know what you're thinking, 'that kid can be so irresponsible!' Please don't think bad of me. I would have done it, I swear! But I was walking down the road yesterday while reading Einstein's book of perfunctory economics, and I noticed these beautiful flowers. I had to make a choice. I knew if I took the time to do my homework then I wouldn't have time to pick those beautiful flowers for someone special to me. So, teacher, I didn't choose to do my homework... I chose YOU!" (at which point you hand her a bouquet of flowers).

She'll be so flattered she won't be able to fail you!
