Long legged monster

If you don't know, you may be one of them, but in this world, there are a lot of monsters. There isn't much of a problem being a monster, and if you want to be friendly, you might choose not to call them that -- what is a 'monster' anyway? But there is no need to be friendly around these parts. I played, learned, and grew like anyone else, with similar friends, so you might've called me normal, that's at least how we viewed each other. Only many years into high school did we learn that not everyone has such long legs. We called the others 'monsters' back then, thinking: "What a weird existence must it be; how could they reach the tree tops or climb steep hills?" When I turned 20 and felt like most at that age that I knew & had seen it all, I decided I wanted to explore the world that allegedly was full of weird monsters, including ones with short legs. Then I started to learn that in those other parts, I was the monster. Even though the short-legged weirdos could use my help with many tasks otherwise performed with uncomfortable or expensive tools, they all ran away. Due to that ostracization, what used to be my benefits became my shame, and slowly, every day, I became a little bit more like the monster I appeared as. Finally, only an unreachable moon accompanied my heroic journey of leisure.
