I used to grow up in brazil and I used to hit macaws with rocks with a wooden slingshot.
Is there any particular reason why you started pelting macaws with rocks?
Hell yeah, I saw a bird fly near a rock.  I almost felt like the rock wanted to be shot at the bird. So I took it, aimed it to the sky and then the rock hit a macaw. I can't believe how many rock slingers there are in Brazil now.
That must have been very neat to grow up in Brazil. You shouldn't have been hurting the defenseless macaws though. If you feel a rock calling you in the future, you might want to tell someone.
Bullshit. That was real, bro.
Whatever justification you think you had, you're still responsible for harming defenseless animals. I don't think many people would believe that a "rock" wanted you to do it either. You're better off ignoring these voices in the future for your own sake, or maybe getting help if you are having unusual thoughts.
