I hate it when you're walking through the forest, and you surprise a small animal of some kind, and you only see it for a fraction of a second as it takes off into some bushes in front of a lake, taking off so quickly that you can't pinpoint its species, even as you move closer for another look and it comes charging at you since you've cornered it, and you move back quickly because you think it might bite you, too quickly to get a species-specific look.

Damn it.
