Two friends, Ron and Tom, were sitting in a cafe — each drinking a cup of coffee.

Ron said to Tom, “I went to this restaurant last night.”

Tom said, “I know — I saw that you checked in there on Foursquare.”

Ron said, “I have to tell you about their fettucini in cream sauce.”

Tom replied, “No need — I read your review on Yelp.”

Ron said, “I heard the funniest joke the other day.”

Tom stopped him, saying “You made it a status update on Facebook, remember?”

Ron looked down at his phone and updated his Twitter status.

Tom took out his phone and sent a reply to Ron’s status.

Neither of them spoke for the rest of the time they sat across from one another, and then they simultaneously just left.
