  1. — Hi, Jeff! How are you?
    — I’m fine, thanks. And how are you?
    — I’m fine, too. How are your children?
    — They are OK. They are swimming in the swimming pool now.
    — Do they always swim on Sundays?
    — Yes, they do and they love it very much.
  2. — Good afternoon, Bob!
    — Good afternoon, Jane.
    — Is Nick at work?
    — No, he isn’t. He never works on Sundays.

    — Good. I take riding lessons too.
