I'm told that I am a very...eccentric person for many reasons. But I usually get weird looks when people see me talking to my pet Betta fish. I don't just verbally speak to them, I also developed some rudimentary sign language. I do a motion and if they understand they will do the correlating motion(s) back to me. Its very simplistic communication and it takes months or even years to get down, provided the fish in question is even smart enough to understand to begin with.
