You are free to be a bit silly in regards to your nonbinary-ness.

Make a joke about your gender. Have a laugh about being nonbinary.

Laughter and humor are not the same as carelessness or apathy. Humor is one of the most powerful weapons against despair.

Embrace it.

(note: neither cis people nor binary trans people get to laugh at or make jokes about us nonbinary folk for being nonbinary. They don’t have clearance.)
