Personally, I'd love to be a shape-shifter.
Why? I'm inspired by my husband's preference for my "green dress." But I don't have a green dress. It's gray.
Things like this make me wonder what it would be like to be in someone else's skin and perceive sensory information differently. Wouldn't it be cool to try out a bat's echolocation strategy?
And if I could shape-shift I definitely would want to try out a mantis shrimp for a while. I mean, 16 types of photoreceptors in the eyes (compared to our measly 4)?! What must your world be like? Plus they are flamin' in the dress department.
Then happy I, that love and am
beloved
