The cat.

The cat is in its corner minding its own damn business.

If you leave the cat alone, it won't even notice your presence.

The cat loves to stay alone and it doesn't care what you're doing, saying or thinking. The cat doesn't need you and does not want anything from you.

The cat is comfortable there, doing what it wants to do.

Don't bother him, and it won't bother you. But if you'll do it, well, you'll get bite and scratch.

I am that cat. So, do not bother me.
