Lexie: Anyone would like to trade presentation dates with me?
July: I haven’t done mine, and I actually would rather do it sooner that later
Niko: I could too
July: But do we trade subjects too?
Niko: I would assume so, they fit particular class’s subject
Lexie: Oh so I can’t stick to my subject and just refer it later?
July: No hon, if it’s about trafficking it’s gotta be when trafficking class is going to be
Lexie: Ding it, I like my subject:D
Niko: Well, you gotta drop it if you need to do it later
Lexie: I have to, I can’t be in class when I’m scheduled
Niko: I think I’m last one in the queue if you wanna postpone it much
July: I’m last but three I think 
Lexie: I don’t wanna be last, July I’ll take yours, you mine?
July: Sure, when are you supposed to speak?
Lexie: April 4th
July: Deal, you take May 5th
Lexie wants to swap her presentaion date. Niko is the last one but she doesn't want to be the last. Lexie will take May 5th and July will take April 4th.
