It's 3-day holiday in Japan. Today, I'd cleaned up my house for a long time. It's oosouji(大掃除) in Japanese. Correct oosouji is done at the end of the year, generally. Well, yes I slacked off. It was difficult to clean under my bed because there was no space for putting cleaning tools in. But finally, I made some space for it after trial and error! It becomes to be easy-cleaning under my bed so I'm very very very happy.
