Gemma: Hey Clara, what are you doing?
Clara: Hi, Gemma. I'm training for a charity event. I'm going to run ten miles on Saturday. Why don't you try it?
Gemma: No, I'm not into running. But I like the idea of helping in charity. What else could I do?
Clara:How about swimming? Or cycling?
Gemma:I'm allergic to exercise. I'm not fit enough.
Clara:Well, you could always try parachuting.
Gemma:You're joking! I'm scared of heights
Clara: Gemma, why don't you just sponsor me and I'll do the hard work
Gemma: OK, It's a deal !
