Although the extremely hot summer weather still continues on, it seems like the chorus of cicadas has toned down a bit, too. That makes me feel that the end of this summer is coming around soon. This year, I didn't go to any summer music festivals or concerts, which was unusual for me. But instead, I watch live concerts through the internet movies on my PC at home and enjoy it, as if I was there. What I gained this summer was "Zoo Volunteering". From the end of this spring, I spend almost all my spare times at the zoo. That made me learn many things about various kinds of animals. And that makes me feel like a professor of zooology. I have gained something this summer, which was something that I hadn't been doing for the past few summers.
