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.
