An Unforgettable Lesson
She was not my close friend.But since then,we become the best friends.
When I was a junior middle school student,a marvelous time I have ever been,I got well with everyone in my class,which means they are all equal to me.One afternoon,when everybody went back home except me and another girl,Lily,I saw she was resting at the table.With concern to the classmate,I stepped forward and asked her what was the matter."Stomache!"She could hardly said a word but to rest.So I carried her home by my bike and sweetly said goodbye to her.I think it was not a big deal for me for I thought it's my duty to heip classmates especially when one couldnot turn to others.
On tomorrow morring,I saw her refrash again and sent her a warm smile.Then as I sit on my desk I found a nice wrapped package with a piece of cute cake inside it.Suprised and touched,I looked back and said thanks gratefully.It was the first time that I felt about friendship deeply.
I could never forget how happy that day even if it was a little thing.
Since then,I have learnt what a help person could bring about.Not only the happiness,but also a forever friendship.

An Unforgettable Lesson
We were never close, but after the incident, we became best friends.
When I was in middle school, one of the best moments of my life, I got along with everyone, and was not bullied in any way. One afternoon, everyone left except for me and this other girl,Lily,I saw her resting at the table.Worried about my classmate, I stepped forward and asked if she is feeling well."Stomache!" Was all she was able to blur out before going back to rest.So I took her home on my bike and sweetly said goodbye to her.I thought it was not a big deal for me for I thought it's my duty to help others, especially when no one is there for them.
The next day,I saw her refreshed again and sent her a warm smile.Then as I sat at my desk, I noticed a nicely wrapped package with a piece of cute cake inside it. Surprised and touched,I looked back and thanked her. It was the first time that I felt that I truly felt a deep friendship.
Even it was just a little gesture of thanks, I could never forget how happy I felt that day.
Since then,I have learned what helping person could bring about. Not only happiness, but also friendship.
*** the last sentence, not only... but also, has to be parallel structure. Which basically means if you used "the" happiness, you have to use "the" friendship. Since there was no adjective to describe happiness, then you need to take out the "forever" since it's an adjective describe the kind of friendship.
