Trail walking etiquette
Person A is walking 3mph, Person B up ahead is walking 2mph.
As Person A approaches, Person B speeds up to 3mph instead of letting Person A pass by.
So they're now awkwardly walking lockstep with each other. Person A, annoyed, stops completely and waits a few minutes for Person B to walk ahead. But the trail doesn't split off anywhere.
Person B slows down to 2mph again and Person A eventually catches up. Again Person B speeds up. This time Person A calls Person B a fucking piece of shit and breaks into a run to get ahead of him. Person B doesn't say anything in response.
