Oh god, the awkwardness of your answer reminded me of the time me and my brother went out to eat once - I'm 8 years older than him, but we look about the same age. He also has really long hair. I'm a cis female, and he's a cis male.

A waitress comes up to us, refers to us as "ladies" - realises one of us is not a lady. She apologised, my brother laughed it off, he gets that sometimes, nbd. She then later made the same mistake again, apologised again, then says "my bad, you guys are a really cute couple!"

My brother quickly made his order because he knew I was cringing my way out of the restaurant at this point, god I really wanted to correct her but the poor girl looked so awkward and uncomfortable already.
