Write me a texting conversation between two people arguing about whether or not they should do something, but don't say until the end what, exactly, they are talking about. Try to make the subject a surprise. The people are Jack and Jill. 
Jack: We should. 
Jill: We shouldn't. 
Jack: It is a great idea, though!
Jill: No. It is gross. 
Jack: Says you. I think it is a delicious idea. 
Jill: Yes, says me. Feel free to enter by yourself if you think it is such a good idea. 
Jack: But I don't want to enter by myself!
Jill: Tough. 
Jack: What can't you just do this one thing for me? Please!
Jill: Because, as I've already said, it is gross, and I don't want to get pie up my nose or something. 
Jack: Well... now that you mention that, it does sound a little gross, but I don't think that would necessarily happen!
Jill: Jack. It is a pie-eating contest where we won't be allowed to use our hands. The pie is probably going to end up all the way in our hair!
