I felt blue after playing table tennis at night. That's because I felt pain on my right knee. As you know I really like table tennis and it is my only happiness. Well, I am getting old, so I have to admit it. Actually, the club members who are older than me wear bandages on their knees. They said that they bought the bandages for the knee in the pharmacy store. I searched for that on the internet last night. There were so many kinds of bandages and their price varies based on brand names. I couldn't choose which one is good for me. In the middle of that, some idea hit me. I bought the bandage for my ankle a long time ago. So, I found it in the closet and wrapped it on my knee. It was a little bit short but it was good, though. I didn't need to spend money for that.
