"You should never's"......have actually happened!!!! Someone (most likely the same person)has actually said or done these things.... Looking back, I guess they are pretty funny(not the drinking and driving one with my kids in the car!).....
I'm not sure if "You should never" is the best way to vent or express.....I thought about using "Have you ever had someone"....... or if "Can you believe" or "Isn't it obvious that......is wrong to do"......hmmmm
However.....I like that "You should never"....is like a piece of advice....
