Suppose you and a friend are out taking a walk and on your way back home you notice a banner at the local convenience store that reads "Mega Millions Lotto Jackpot: $280 Million!!!". You want to buy a ticket, but you don't have any cash on you. You ask your friend if she can loan you a dollar to buy a ticket and you'll pay her back as soon as you get back to the house. She loans you the dollar, but she admonishes you for wasting your money a stupid ticket that has odds of winning of 8 million to 1. You don't care, you're living for the moment and taking a chance at winning millions so you buy your ticket.
When you get back home, you immediately repay the $1 loan as promised and go on with your day. Later that night, you tune into the local news to get the winning numbers. Obviously this scenario ends up with you having all the numbers AND the mega number and you win a whole lot of money! You're so excited that you immediately call your friend to tell her about your incredibly lucky lotto ticket. She of course is thrilled and she can't believe your good fortune! Her response is "This would have never happened if I hadn't loaned you that dollar, you know?" You can tell what she's getting at. She thinks she's entitled to a cut of your winnings. If I were in this situation, I might give my friend a few dollars or I might just buy her a nice gift, but I wouldn't feel obligated to do either. What would you do?
