My brother is the same way. It’s not as fun as you think. Everyone else is like, oh man, this was disappointing, I worry about that, maybe we need this, etc. My brother just stops talking and leaves. The next game he’s right back, 100% sure of victory again. Didn’t process what happpened at all. Doesn’t feel anxious anticipation. Just sits down with no excitement, completely assured of another victory. It’s actually maddening, believe it or not.
