Happiness? What's That‪?‬

Humoristic Fantasy. Short story:

It was just another day. An old witch sat on her terrace sipping a shot of espresso. Her espresso never ended until she wanted it to. That's how it is with witches. Her eyes followed an approaching figure. It was an elf who used to come over…every few years.
"Ufff…" said the Elf and sat down beside her.
"What's bothering you today?" asked the Witch.
"I do nothing. Nothing, nothing, nothing, all day and every day. I just love to do nothing! And then…I catch myself with no peace of mind. You know, like I enjoy it very much but still something's bothering me. Something just doesn't let me float freely and weightlessly into this lovely nothingness."
"Hmmm…" said the Witch. "As addicted to freedom, you might be happy being free and doing nothing. Right?"
