In the lottery, numbers that are close by often win; that's unfortunate. I can regret what would have happened if I had bet on something next to him. For me, this is a common reason, as if someone is laughing and teasing. However, I don't see the point in being stubborn, betting on the same numbers, or figuring out some strategy. It's probably easier to change your thinking. Today you bet on even numbers, and tomorrow on something divisible by three. In all cases, I don't think it's possible to somehow figure it out; the root cause will always be the luck that chooses us at a certain moment.
