The worst ridiculous and ugliest moment I have ever encountered pertaining gambling is when a friend told me and few other friends that he was going to take responsibility of the bills for our weekend hangout.
He had us that confidence to be unfailingly.
Guess what???
It was actually from a game he booked against the weekend that had him that morale to had projected this weekend hangout amongst us and it was not that he had secured the money to be assured.
As a matter of fact, he was nowhere to be found all through the weekend and could not even take his calls because he felt messed up of himself for the false promises.
While time passes by, you can imagine how he narrated the stories and felt remorseful of being a d!ck head as the game failed him as predicted.
That is clearly a case of over confidence. Not only he assumed that he is going to win but also announced it to their friends.
He must really be foolish at that time but I hope he learnt from this situation and took it as a lesson to not depend on gambling completely.
Not only just over confidence, I think the guy wanted to prove something, and that's something like "hey, I'm good at this and you my friends should follow me next time". Or maybe the guy was struggling financially and so envious about his friend's achievements, so he counted his eggs before it hatched, then promised his friends over the weekend and then lost everything eventually. OR maybe most likely, he was promised that he was betting on a fixed match and the probability of winning is 100%.
