Boy , we had a lot of rain here in the Kanto area yesterday ! And strong wind , too . I never left my apartment , which for me happens maybe twice a year , when either I am really sick or the weather makes it absolutely miserable to go out . The rain was supposed to start Monday morning , but the front slowed down before it got to Kanto and it did n't really start here until Monday night .
Why did they stay inside all day ?
