My T and I usually talk until we're both completely exhausted...and then one of us says something like "Oh man! Its LATE! We better get going in a few minutes." Then 20 minutes later we say something like, "We REALLY need to get going...its late." Then eventually we get wrapped up, we are both horrible about time. And she says something like "Well THAT went by too fast." Then we walk to the door, chit chat a little bit more about something fun, and eventually make it out the door with a hug
