Maybe I have to go to the bathroom and I see a janitor making their way towards the same bathroom. We both start an all out sprint for the bathroom door. In this moment we are both adversaries, but his goal is to clean and my goal is to evacuate my bowels. Sure we are competing for the same resource, the bathroom, but our objectives with the bathroom are different. You could also say we are almost playing a different game, he’s trying to not spill his mop bucket and I’m clenching my cheeks.
