Dear Sue,
There is a problem between me and my good friend. We used to study and take (锻炼) together, but ever since last Friday,she hasn't (邀请) me to go with her. I considered all the things that made her have a headache about staying with me, but I haven't found out the reason (还,尚). We never (打架)or even quarreled with each other. I tried to (交流) with her, but she refused to answer. My heart is broken and I' m(期待)you to help me.
