“Suffering produces endurance.”
The doctor’s diagnosis was wrong, and the steroids he prescribed have puffed your face up like a chipmunk for two weeks and accomplished nothing. The car had to go to the mechanic again, and you’re pretty sure it’s for the same thing you just got “fixed” three months ago. You spent more time stuck on the highway in heavy traffic today listening to the clatter from your wheel well than you spent on the job.
You are somewhat less than amused.
