I was sick.......

In last weekend, I felt so discomfort that I couldn't do any outdoor activity. I think I was sick. At first, I just think maybe I was too tired. For a short time, I started to have a cough, and then I have a headache,too. It's make me more difficult to do what I planed to do on the weekend. After the weekend was over, I left a lot of homework which was undone. I must to keep my health well or everything will delate for a reason of I was sick.
