I'm a shellfish!

I was reading a story to Claire about the different types of fish in the ocean and found I related to the shellfish. The book said a shellfish has a hard outside to protect its soft, beautiful, fragile inside. A shellfish keeps its shell open but shuts immediately if it senses danger.
The book Shellfish Aren't Fish by Alan Fowler is me in a nutshell.
No, I don't live in the bottom of the ocean, but I have many similarities with the shellfish. Clams and oysters have ugly outsides, but beautiful pearl on the inside of their shell. While some people might be impressed with my outside, I believe all my best attributes are inside.
Rather than focusing on hair and makeup, I always focus on relationships and helping people out. I, too, keep my mind and spirit open, but close myself off when I sense ugliness.
The shellfish opens itself back up when danger passes it, but unfortunately, I am not that brave. Once I close up, it takes time and effort to open back up.
"Every mollusk makes its own shell. So in a way, a mollusk's home--its shell-- is a part of the animal."
Isn't that true about humans? I believe we, too, make our own shells that become part of our self.
"Sometimes a grain of sand gets inside a bivalve's shell. When it rubs against the animal's soft body, the bivalve coats it with a smooth material called mother-of-pearl."
So when something small gets inside the oyster and irritates it, the oyster turns it into something beautiful. That is something I would like to do.
