I betcha!

"You will."

"I won't."

"Oh, but you will. You just don't know it yet."

"Man, chill yo flesh. I told you that I won't and I mean it. Agree we disagree?"

"I agree, but I know you will. You're just not there yet. You're in denial."

"Funny, 'cause I believe you're the one in denial. Man, are you actually telling me that you know me better than I do myself? Are you for real?"

"And I believe you're being arrogant and selfish. Look, I'm willing to bet on it. When the time comes you will. No doubt about it."

"How much?"

"50 euros."

"Well, why so little? How about we make this a 400?"

"Come on Mal! I know you won't be able to pay up a sum like that..."

"... but you will. Look, I promise to pay up if I lose."

"Okay then."

Handshake.

And time flew by and when it finally came to it Malisky didn't. Quite effortlessly, really. You see, she never had a change of heart about it.

"I can't believe you didn't."

"I know. What a shocker. You owe me 400 euros and I expect you to pay up, because this is me being arrogant for real this time."

Moral lessons of this story:

1) Don't make bets when the other person is merely investing.

2) Believe your friend in what he's/she's/they're saying in case they truly fucking mean it and don't criticise them rudely when they never intended to offend you, until you did. Just accept it. You disagree in some things. If you can't and it bothers you, wave bye-bye. It's all for the better.
