A：Are you going to the school party?
B：Yes, I am.     69    
A：You can’t do that!
B：    70    
A：If you wear your jeans to the party, the teachers won’t let you in.
B：OK, then let’s take some snacks.
A：    71    
B：Really? Why?
A：    72    
B：Oh, I see.    73    
A：Yes, of course . If we don’t have our ID cards, we can’t go to the party.

The teachers will take them away if we do that. Do we have to bring our ID cards? What will happen if I do? No, we can’t do that, either. Are you free tonight? I am going to wear my new jeans! What’s your plan?
