Tails

I feel like the world would be a better place if we all had tails and like if we got happy they would wag and stuff like imagine how much easier it would be to convey emotion but like when I would notice my tail wagging I would get embarrassed and shit, but I feel still like I would want one so when I talk to someone I enjoy being around it starts wagging and like they just assured that I don't hate them or something, do yall understand?
