My current supervisor has been trying for years to get me to appreciate her weird flex of putting in 16 hour days 6 days a week. She practically lives at our office and wants everyone there to know it.
She still acts shocked and saddened when I respond to her self-torture brags with "That sounds really unhealthy. I'd never let my job do that to me. Gotta put your oxygen mask on first. I wish you'd take care of yourself." Like it's the first time I've said it.
I guess its the lack of sleep that keeps her from remembering that I openly consider her flex to be the opposite of a flex, and look on her behavior purely with pity.
