Master Negotiator

Dad: Your weight loss has come along well, what are you down to?
Me: About 260.  I have another 50 or so pounds to go.
Dad: Then what?
Me: I’ll probably get an abdomenoplasty to get rid of the extra skin.
Dad: I’ll pay for it.
Me: It’ll probably cost around $7000.
Dad: I’l pay for half of it.
Me: Deal.
