英语书面表达80字.要求写某人帮助你的事件,写你对他的感谢之情,写你对他的美

It is always nice to be helpful to people,I truly believe that.Sometimes it is just a tiniest minor matter,but it can change somebody's day or even life.There was once I went school to take my final exam with an extremely bad mood.I had a fight with my mother,had failed two exams,and more unfortunately,I forgot my pen.I knew the teacher was going to tease me if I ask them for a pen,so I decided to leave.And then when I was packing up,I saw a pen lying on the desk.It wasn't mine and I had no idea who put it there.I took that exam because of that pen and I never thought about give up ever after.That pen gave me courage and patience.Maybe I won't finish high school if there wasn't that pen,if there wasn't this help me with a pen.So,you see,helping people can change a lot.I wish the one who helps me happiness
