hafta - A word you use when you’ve got all day and no one is yelling

A word you use when you’ve got all day and no one is yelling at you, like when you’re relaxing and your life is perfect.

I hafta do this later, so I’m just sitting here doing nothing.

I hafta finish my homework, but I’m taking my time.

I hafta go to school, but I’m not in a rush.
