You’re right, but your example is putting you in the category of people you’re explaining. You couldn’t find a single better example? Really?

Here’s one: People at the metro will try to get on before others get off. They will just push their way past them like if they don’t get on right this second then the train will leave without them. It makes it harder for everyone else and the whole scenario is easy to see from all perspectives, yet they still miss it. No guessing reasons, just moronic selfishness.
