Kate: you home?
Caroline: No, why?
Kate: Oh, I'm just in the neighborhood and I thought we might grab a quick cup of coffee or sth.
Caroline: That''s a pity... I'll be back in 2 hours..
Kate: OK, next time maybe :)
Caroline: definitely!
Caroline will be back home in 2 hours, so she won't meet with Katie who's in her neighborhood right now.
