英文小作文：

Foul Up My Day

Today I had a terrible day. I was supposed to help my friend with her homework, but I really fouled it up. She ended up having to do it all over again, and I felt so bad about it. I also messed up my own work because I was so nervous about the situation. I don"t know what came over me, but I hope I can learn from this experience and not make the same mistakes again.
