I have been waiting

Today the weather is very hot. I have been staying near a tree to protect myself from the sunshine. I have been waiting in the street for a long time for my sister. I have been staying near a tree to protect myself from the sunshine. I have been thirsty because I didn't drink water for 2 hours. I looked around but I could not see any store or any cafe. She called me and said that she was sorry, and that she hadn't been able to come because she had been working for that time. I said that it was okay, and asked her whether she would be here soon. She said that she couldn't. She has been going home for 10 minutes. She decided not to come because she was tired. She just wanted to lie down on the couch and watch TV. She had promised to teach me how to drive a car. Now I have to wait to learn how to drive a car until next week.
