 to the history of reinforcement. This is where this, I forget. Hold on, I need a cue. Oh, that's it, history of reinforcement is just the things that you've done in your past. It's what you bring to the table, it's our history, it's what we've done, it's who we are. And since we've been around so long, the more experiences you have, the bigger the history of reinforcement, it all speaks to your behavioral repertoire. And when we know what your behavioral repertoire is, when we know what you can do, we can start to go and wonder what reinforcement history produced, that sort of responding. We can only guess, but all the things that you have experienced is your reinforcement history. It's a great fun little thing to say. Please tell me about your reinforcement history. I would like to hear.
