The construction
doen + adjective (like
doe normaal,
doe gek, or
doe aardig) is a special case in Dutch grammar. When you use
doen with an adjective, the adjective describes something about the subject’s behavior — not the person themselves, just their behavior. [

To make things more complex,
gewoon/normaal are exceptional amongst these
doen constructions because they “simply express a state of affairs.” They are neutral commands while other
doen + adjective combinations carry negative connotations or implications of insincerity.[

Jap is aardig =
Jap is nice.Jap doet aardig = Jap does nice,
Jap is behaving in a manner that is nice, but he is not sincere.So “doe normaal” is commanding you to make your behavior in a state of normalness. The question remains: normal according to whom? Your own standards or society’s?
Unfortunately, the grammar doesn’t really answer that definitively, so I have no choice but to accept the context-dependent take on things.
My husband gave me a perfect example to illustrate this: Let’s say you’re going out with a friend to an event where the other guests are likely to wear boots, flats, or heels. You normally wear close-toed flats so you opt for a classy pair that look good with your dress.
When asked her opinion, you friend says, “Ah nee, doe normaal.” Here, this means “behave in a socially acceptable way. Don’t embarrass yourself.”
But if you were to instead choose heels, and your friend says, “Nee! Doe normaal!” it would mean, “Do what you normally do and stick with flats. Be comfortable.”
