What if you began the sentence with почему?

Почему (же) вы вовремя не писали, на приёме?

Is there a difference in politeness here, if you use же, or don't use it?
же form is still more polite
When you add же to this specific question that makes it "an asking"
if you remove же this sentence becomes "a demand" to answer
