Ex Input:
M: So Alice, when do you begin? ,F: I start on the twenty-first. I'm hoping to hurry to the coast before I'm too busy. ,M: I don't blame you, you're going to be working long hours, and should get a little rest before it all starts. ,F: We don't actually start working on the first day, but there's going to be some hard training. All new volunteers are required to complete 10 days of training, so I do want to get a little play time before that.

(B) M: So, you think the voluntary work is tiring and you do want to get a little play time before training?

Would you slow down, please?
