This was a recent conversation that I had with my girlfriend’s father, who knows I do web design.
Father: I have a business idea. How hard is it to make a Facebook?
Me: Oh, that's simple, not hard at all.
Girlfriend: No, he doesn’t mean to make a Facebook profile. He means to redo ALL of Facebook.
Me: Oh. In that case, that's very hard.
Father: Oh, okay. (Pause) What are we talking then, maybe just 3 to 5 hours?
