Client: I need this by Thursday.

Me: Shouldn’t be a problem; I can have it done by Wednesday.

Client: No, you’re misunderstanding. Not Wednesday, Thursday.

Me: I meant that I’ll get it to you earlier than next Thursday.

Client: And I meant that I need this by Thursday.

Me: Okay, I’ll send it next Thursday, then.

Client: You’re just not getting it. I need it by THIS Thursday.

Me: But today’s Thursday…

Client: Yeah, which makes all this time you’re wasting so confusing.
