I had one with a classmate today via email.
CM: mbbored, can I borrow your statistics textbook?
Me: Sure! Are you going to be at the seminar tomorrow? I can bring it to you then.
CM: dep. fac? no fac? pref off, use copy.
Me: Excuse me? Did you mean to respond with that?
Me: I didn't understand your email.
CM: What didn't you understand?
Me: Any of it.
CM: I asked to borrow a textbook.
Me: And I said yes. Then I asked you if you'd be at seminar so I could hand it off to you.
CM: And I said, it depends on whether or not the faculty will be there. I prefer to meet you at your office, where maybe I could use your copier.
Me: I did not get any of that.
CM: You should really study shorthand.
Yeah, shorthand was the problem there.
