I Could be a Sonnet

I could be the Moon, with a friendly face,
But it gets quite dark and cold during night.
I could be the Sun, shining down from space,
But it would be too hot and much too bright.

I could be a lion so brave and strong,
But most are afraid of teeth and power.
I could be a blue bird, a happy song,
But by dawn my notes would be quite so sour.

I could be a mouse; I could be a cat.
I could be a weed; I could be a rose.
I could be a boot; I could be a hat.
I could be a mouth; I could be a nose.

There are so many things that I could be,
But I think I will choose to just be me.
