My foot was hurt, and I can't go anywhere now. :/ It's the second week since I hurt my foot. I still can't walk normally. There days I trying to study English, but I find I can't focus on it, and lack of efficiency. Today I even didn't finish reading a article. I really need to get exercise, and go outside breathe some fresh air. Just sitting on the chair is so boring. I now understand having a healthy body is really a kind of happiness.
