ATO

ATO: all talked out. This is the moment while you are engaged in conversation that it just hits you, you no longer wish to be talking to that person any more. It's not necessarily them (although it could be depending on the fellow conversationalist), but you have reached your human contact limit for the day and they just keep babbling. You are entirely saturated with the utterances of the English language—your verbal pot is full and you are reaching your boiling point. All you really want to say is "stop talking, I just can't listen anymore." You find yourself getting antsy and you have ceased listening to them altogether. Then, you just blurt out, "Great catching up with you. Talk to you soon." These words come out of your mouth subconsciously, interrupting them in the middle of their tale of woe, promptly ending the conversation before they could wipe the tears from their eyes.

ATO is worse over the phone then in person. Do your caller a favor when you are nearing ATO status, just don't answer. You will have a better conversation with them at a later time and, hey, they may actually enjoy talking to you when you don't prematurely end your gab sessions.
