I can swap my ax for my bow and shoot a greyling with scarcely a break. Or I can just include the little fish dropping in my swing.

Being annoyed is a choice.

Being annoyed is a feeling.

The choice is what you do with that feeling. I personally call out their cowardice to fight man to...twig, or ignore them and run along to continue my objective. OP has chosen to seek like minded individuals to confirm there are others who feel this way.
