I accidentally greeted a stranger like we were best friends

I was walking into my apartment building when I saw a woman who looked exactly like my friend from behind. Same hair, same jacket, same bag. Without thinking, I shouted, “HEY QUEEN!”

She turned around.
She was absolutely not my friend.

She gave me a polite but deeply confused half-smile while I panicked and blurted out, “Sorry, I thought you were someone else… who is also… a queen?”

I then pretended to check my mailbox even though I already had my mail. Twice.
