It's a long story...

No, actually it's not a long story. It's just a story you don't want to tell me.

Have you ever had someone, after saying, "Oh, it's a looong story," change their mind and decide to tell you said story? It's never long! It's just personal, and perhaps incriminating.

I'm going to start calling people out on this one. You should join me; it's going to be a load of fun!
