Ryan was trying to talk me into buying him something. He said, "If you buy it for me, I will clean the rat cage."
"No," I told him. "That's your job. You don't get a bonus for that."
"What if I vacuum the living room and empty the dishwasher? For a week."
"Hmmm" I said, thinking it over. "That's almost worth it."
Sensing weakness, he pulled out all stops. "If you buy it for me, I will vacuum the living room, empty the dishwasher and I will let you take a picture of me riding a horse in my mask."
Weeks passed. Ryan got his prize, but I did not get my picture. Every time I asked him to go to the barn with me, he had an excuse. Some were legit. Some were not. I didn't force the issue and I didn't get mad. I just kept on asking.
Finally, he said, "You're never going to forget about this are you?"
"No," I told him. "It has to be done."
He sighed theatrically and said, "Fine. Let's go to the barn."
Best deal I ever made.
