If you can't wait to play gambling but anonymously, there are enough casinos on the Internet that do not require users KYC.
In that situation I do get into fight, not like fists and all, I do not like that and try to avoid that as much as I can because violence is never the solution, but I do argue with them and make sure that it doesn't happen, no matter what the consequences are.
Friends are very necessary, but partly when we are in a casino game, or sports betting, we must be clear about something that if we do it as a couple we must set the rules and not break them, because what is risked is money and when there is money from through there are people who forget friendship and act in a very radical way, that has been a witness to how things and business can end badly.
When you decide to make sports bets with the capital of both people, always for any movement you must notify the person of the movement or bet that you want to make, this so that the bet that is made is lost or won, both are satisfied with what it was decided, otherwise if the other party says no, then you should not do it, this is what makes the two people work in harmony, that is why I have always played and placed my bets alone, without having to give Explanations to no one, if I lose it is because of my responsibility and if I win then too, but it is very different than working with another person, for everything you have to notify, that is the secret of this.
I've got to agree with you on your "lone wolf" approach though. If you win, the glory is all yours. If you lose, you've only got yourself to blame. No messy explanations, no hurt feelings. Just the game, the thrill, and you. Aint that a better bet to place?
