Are you enjoying your life in Japan ? I have big news. Three weeks ago, I joined a volunteer group ( 3 ). We usually go to mountains or rivers near our town and clean them, because birds and animals sometimes eat the garbage there. We know it is not good for them. Also, in winter, we will go to one of the lakes and see how many birds there are. I heard there were about 500 birds last year. I hope this winter we will see more birds than last winter. We only do small things, but I believe that doing small things is important. Last night, I told my grandmother about our group. She enjoyed listening to me. She loves flowers and birds very much, but she uses a wheelchair now. She doesn't go out very often to enjoy nature. Then I came up with an idea. I am going to ask our volunteer group to go hiking with people like her and help them. It will be (5 if we can do so! I think she will be 6 to go with us. I will write about it next time.

Her group collects used kitchen oil and makes soap from it. Oh, it's good for nature. Do you think we can join the group? I don't know. Shall I ask her about it?
