We divided the bill into six equal parts regardless of who got what but we didn't have enough small bills between us to have it work out.

"I owe you five."

"Whatever"

Later, walking down the street he again mentions that he owes me. My friends owe me nothing and he knows this so I said "I usually settle your debts with your wife."

"Oh really? I'll call her right now and tell her" he said as he raised his dialed cell phone to his ear. "Hi, Honey. Timmy said he usually settles my debts with you....Okay, bye."

He didn't tell me what his wife said that night and by the next day he didn't remember the phone call.

Hopefully his wife forgets as well.
