WISDOM BITS - the only answer to "Why do you treat me this well?" asked by a more miserable person

This may happen sooner or later, and it'll be awkward for people used with misery to be behaved with differently than they ever knew. So they might try to test the water, but never forget, even if they want to check what your behaviour is (as a different one than they may have ever experienced) this may not end up as a pleasant experience, since they are still used with misery, so they most likely don't know how to treat you better.
