Mr. I-Don't-Care monster

This is Mr. "I Don't Care"
It's not that he doesn't care what people think
Because he really does
It's just often times what he hears is "I don't care"
When he says what's on his mind.
So he tries to be
As quiet as can be
So not to upset anyone
He rather have everyone think he's fine instead of hearing
"I don't care"
He is very lonely, grumpy, and often times angry inside...
But you don't care.
