You're just going with the flow because you're too tired to fight anymore.

I got fired and my cat knocked over my coffee. Hair hit the hide, I'm just gonna nap.

My phone died in the middle of a Zoom call. Hair hit the hide, I'm gonna fake my death.

My pants fell down in front of my boss. Hair hit the hide, I’m just gonna be cool about it.
