Shopping

I think Japanese are very wastful when they are move to another place. They will waste some funiture even if they are new. They never thought that they can't use it in a near future because it isn't the source that we can use forever. Do you know the supermarket near my house won't give me the shopping bag. It cost me 5 yen to get it. I think this is a good idea to help our environment. However, when I forget my bag, I will lost 5 yen. Today, global warming is the problem of the earth.  I realized I bought some thing I don't need it in the past. I thought why I bought it. I promise I won't buy anything if i don't need it. Did you ever buy anything you didn't need it?
