I am making Emily some chocolate milk

"Dad, you're doing it all wrong!"

"How's that darling?"

"You're supposed to put in a little bit of milk with the chocolate powder and then use the mixer* and then pour in milk up to the top."

"Do you think it makes any difference, darling?"

"Of course it makes a difference. You've put all the milk in before putting in the chocolate powder, so now if you use the mixer it won't make it frothy enough and the milk will go everywhere."

"Hmmm. You could be right. Never mind, I just won't use the mixer. I'll stir in the powder with a spoon. That'll be alright, won't it."

"Nooo!!! Then it won't have any bubbles at all! Oh why can't you do it properly."

[Mildly] "Darling, you're complaining rather a lot."

"Because you keep doing it wrong! If you did it right then I wouldn't have to complain, would !?"

I'm sure there must be a flaw in her argument somewhere. Perhaps something to do with respecting your elders or doing unto others as you would like them to do unto you, but unfortunately her logic seems quite unassailable to me...
