I gamble alone, not because I prefer it that way precisely, but because of pure chance. In fact, some of my friends love betting on sports (on sports that I don't like, unfortunately) or gamble but in platforms or physical locations I don't like. So, although I would like to have some friends I could talk to about my gambling experiences, the most similar experience I find it in this forum.
I have friends too that share common interest in gambling and sports betting as well. But I don't want to be with them if it's about my personal bets and gambling activities.
While them, they don't mind sharing it to me on how they're doing and how much they're winning and which bets that they are on.
And so, I prefer to be alone because I think that it's invading my personal space if I get along with them or it's just me that becomes irritated when I have them with me and trying to meddle with my bets.
