Either my love for animals or my love for anything aquatic. I have a mermaid table with shells I found on the beach as a child, mermaid ceramics, a Galileo thermometer and tons of other ocean related trinkets. When I graduate from college, my goldfish, will swim around in his aquarium with the friends I get him. People call me a mermaid because I love water so much.
I also dream of having a huuuuuuuge house one day just so I can fill it with animals. I already have cats, dogs and fish, but I'd also want bunnies, turtles(Depending on my state... In some states, they are illegal! O_O), frogs and so much more!
