It was so nice of us to throw away an other person's garbage:) lol
I think that we, Japanese use too much plastic bags when we go shopping. So some supermarkets use less plastic bags and ask customers to bring recyclable bags, and I think that is a very good idea :) So when i usually go shopping i try to bring recyclable bags and don't get any new plastic ones.
we need to save the environment :)!
