When you deeply dislike someone, they have as much power over your thoughts as those you love.
Those people don’t deserve to have any room in my thoughts, so letting them push me into gambling is giving them way more power over me than I am willing to give.
If I were to blame someone for making me gamble, that is a copout. They might make me want to gamble, but to act on that trigger is all me. No-one can choose to do that for me.
