Tina and I had been good friend for years. We often did things together, so one day Tina didn’t talk to me and just sat by herself. I don’t know what was wrong. I thought about what I had done and said recent. Was Tina upset because I had done well in the history test than her? No, she was happy that I did well in school. I decided find out what was the matter. I walked over to there Tina was sitting. “Tina,” I said softly, “is anything wrong?” He answered sadly, “Yes, my cat died on last night.” I finally knew the reason what she didn’t talk to me and comforted her.
