Phil: Hey. I'm not going to the lectures today.
Andy: Ok. Someting's cropped up?
Phil: I want to stay home.
Andy: :-)
Phil: Look out the window. Grey, drizzly, cold. Not very tempting to go out.
Andy: Well, I'm going. Bad weather or not.
Phil: Ok. Will you share the notes later?
Andy: :-) 
Phil: I know it's unfair... I'm sorry
Andy: Have I ever kept my notes for myself only?
Phil: No, you're a good friend. Thanks, pal!
Andy: Ok. Must be going. Bye.
Phil: Bye.
Phil isn't going to the lectures today because the weather is bad. Nevertheless, Andy is going and will share his notes with Phil.
