Is this real or just a story?
Charles was foolish. How would he trust friend up to that extent? That is foolishness. We should not handle life with foolishness, bet separately.
Kelvin is now rich. If Charles is not rich, Kelvin may win anything brought up by Charles, except if Charles is rich and able to file a law suit with Kelvin. But even where is the evidence that they added money together to bet.
Absolutely delusional story from beginning to end - the author did not even come up with a reason why they made a "joint" bet, and did not bet like normal people separately. The situation with money is also unclear - judging by the fact that they bet on one game, they were already high rollers and they had some money. And another thing that hit me was the "big house in another state." Apparently it's not about the USA, otherwise what kind of state is it where for 120k dollars you can afford a big house (presumably not in the forest)?
