During the last Real Madrid game, I bet my friend that if Real Madrid lost, he would pay for the snacks, and if Lille won, I would do the same. As you know, Real Madrid lost, but when the game ended, I was too shy to remind him to honor the agreement.
He is your friend, and why do you have to be shy? Gambling like this is always interesting, and I do prefer we watch the match together. Immediately after the match ends, I will remind the person about the bet that we placed, and he should fulfill it. Sometimes if we bet and I win, I will remind the person that the bet is in favor of me, but I don’t really ask them to fulfill their promise, but I am not always shy to tell them they lose, and I win.
Since the person is your friend, you don’t have to be shy, you will ask him to forget about the agreement you people had, but I see no reason why you have to be shy since you called the person your friend, and I am sure arguments is what’s going to make you guys place that kind of bet.
