多谢Caliber和老猫指点，看这样写行不行

We are A’s parents. This letter is to report that our daughter, A, was hurt in the school. A said B pushed her down to the floor and kicked her on Monday, March 26, 2009. A lot of students saw the incident. A said she never did anything unfriendly to B. There are two pieces of skin hurts in A's right leg. We took the picture as evidence. Please review the picture. The picture was taken on March 26, 2009.

We need a fair resolution for this incident. We require that B and her parents apologize for her violence and promise not to do it again.

看来还是专业人士眼光敏锐，一下就能指出要点。
