Negotiation

My current photography assignment is a self portrait.  It's difficult.  Not just the context, but physically taking a picture of myself with a 35mm film camera.  I had an idea, set up the camera on a tri-pod, set up the lighting, attached the shutter release cord and then realized the cord was only about 8 inches long.
Help!
So I snagged Heidi off the couch and asked her to come help me.  All she had to do was press the button.  Well, she whimpered, and whined, and complained that it was going to be boring.  I tried to bribe her with fruit snacks, crackers with the nasty cheesy spread.  Nothing.  Finally I offered five pennies.  Her little ears perked up.  She looked at me, realized she had the upper hand and said, "Fine.  But I want ten more."  Fifteen pennies it is.
Heidi pushed the button 36 times at my command.  I thanked her and sent her off on her way.  Before she left the room, Heidi turned to me and said, "Actually, I really wanted a dollar."
I gave her 15 pennies and I'm looking into Pre-Law Kindergarten.
