Why is it so hot in the classroom?

Hi, my dear friend! How are you?How did you spend your summer vacation? ? And I carried out them most productively and it is useful. I not simply for days on end sat at the computer, the TV, went simply to the street. I helped the parents about the house. I asked them to give me a task and I carried out it diligently. In the middle of the summer I spent summer vacation in the countryside. There very much it was pleasant to me. Fresh air, beauty of the wood, warm water of the lake. There I got acquainted and made friends with boys and girls. There it was very interesting as every day it was filled a set of events. In the afternoon we went to the lake, to the wood, gathered mushrooms. In the evening we watched animated films or movies, danced in discos. This summer very much it was pleasant to me as I spent summer vacation. I think that academic year will be interesting, and I too will try to spend it it is useful for itself and surrounding me people.  But during this time I very much missed you, I wait for your answer rather.
