If I want to brush my daughter's hair and if she puts her hands on her head in order to prevent me from doing so, can I say "take your hands off!"?
But it's also a sign for you to brush more gently!
You can add "Honey, let me do this, or you will look like a squirrel has built a nest on top of your head."
I'm sure I've said similar things.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
It seems to me, an ageing, past-his-sell-by-date Brit, that your response reveals a characteristic of Americans at times, that of shying away from calling a spade a spade.
I have noticed, for example, TheParser's* attempts to avoid giving offence to anybody, something I noticed with my American trainees when I worked on Cert TESOL/TEFL courses. You seem to bend over backwards at times to avoid the appearance of intending offence, when sometimes (I feel) a short answer serves the purpose admirably. In my opinion, if the listener takes offence, that's his/her problem, not mine.
*Sorry Parser, nothing personal.
