To Kentaro:
In summer while I'm in my house, I turn on an air conditioner, and while I'm out, I find a place where an air-conditioning is on and enter it. I'm sorry my answer is too simple.
My special memory in summer was a training camp of the dance club that I belonged to when I was in high school. It was a six-day camp. We went running before we ate breakfast. After we had breakfast, we did muscle training. In the afternoon we practiced dancing and at night we created dances. It was so busy that we couldn't eat food and take a shower being relax and sleep like a log. It was too hard, but hardship will be our food in the future, right? So now I'm a sum of the experience. It was an unforgettable memory.
