Two days ago my dog Fritz [?] (to sleep) all day. When he [?] (to get up), he [?] (to look) out of the window and [?] (to see) that it [?] (to rain). Since then, he [?] (not to eat) anything. He [?] (to be) a stupid dog all his life, and so I [?] (not to be worried) when I noticed that he [?] (to behave) stupidly that day, too.
