I imagine many Japanese people are busy today cleaning. Not me! I prefer to wait until Spring when I can open all the windows, let the fresh air in, and get the dust out. I vacuum behind the furniture, wash the windows, dust everything off, and make everything "spic-and-span". American people call it "Spring Cleaning". By the way, where have all the Christmas decorations gone? I went out last night and couldn't find any anywhere! American people are quite lazy about putting them away. Sometimes, you can find Christmas decorations still hanging in the end of January!
