It's because most people are closed minded in the "connections with animals" department. If it's not cute and furry, you can't have a relationship with it. But those people are just depriving themselves of the opportunity to experience different types of love and affection from other living things. Don't feel crazy, or weird, or beneath others because of how much you love your fish. I talk to ALL my animals, and yea it might be strange to a lot of people, but I don't care because I love them, so I'm going to express that. And plus, you have all the people here on this forum to remind you that you aren't alone. :)
Kindness and respect should be shown to all animals, no matter if they are furry, scaly, big, or small. Be a hero to the animals and GO VEGAN!
