SO MANY HOMEWORK!

once my teacher told me that I did not finish my homework. And...I did, and I checked my homework book. I DIDN'T DO IT?!?!?! And that is bc there is TOO MUCH HOMEWORK! So when I checked my homework, I didn't see it. Why does teachers give us so much homework? But today I am lucky bc I did a lot of homework at school. So I can use the computer. And idk what to write...and I have a dictation at Thursday (22/4) .WHY EVERY WEEK?????????!!!!!!!!!!!!???????
