My conversations usually go something like this:
How was your weekend?
It was good, we took Gu----
Of course, it takes experience to know that you are the sole participant in the conversation at this point, because, more often than not, the person who asked the question is still standing in the doorway to your office. To the amateur, this person's presence might indicate that he is listening, but in his mind, he is wondering what would happen if he Googled the words "puerto rican sandwich balls."
Trust me. He is not with you. You might as well just save your breath.
Or, you could have a little fun.
"How was your weekend?"
"It was good. We had dinner at Las Fiestas Friday night, and by Saturday morning, I was pretty much setting the world on fire. With my butt. Out of curiosity, have you ever farted while wearing a plastic disposable G-string? Whole different ball game, dude. It makes this sweet snapping sound. Really. Good times. My dog about busted a gut laughing. And he rarely even smiles."
"All right then, I'll catch up with you later."
"Cool, have a good day."
