Harry, let's play some ping-pong today.
I'd love to play a set or two, but my right arm hurts. I've decided to stop playing ping-pong until it feels better.
Well, how about going skating?
I'd like to, but my knee hurts, too.
Harry, stop making excuses! You're just lazy.
No, I'm not! You know, there's a basketball match on TV today. Let's just stay home and watch it.
