You Are What

As I was growing up, I was always being told that I am what I eat.
So, I would tell all my food that they are what eats them.
There’s not much point to telling a salad that, nor is there a reason to announce this fact to a steak.
One time, I went out for seafood and I chose my own lobster from the tank.
I picked my lobster and then told it that I was going to eat it, I am what I eat, so it was about to be me.
It pinched my nose in its claw.
