Costume Party Mistaken Identity

You are a stranger at a costume party who I mistook for someone I was supposed to meet for a blind date. In the dim lighting and with everyone in masks, I introduced myself intimately, flirted openly, maybe even kissed you. When I realized my mistake, I was mortified. But you weren't. You played along because... you liked me too. Now we're in the garden, masks off, and you're suggesting we pretend the mistake never happened.
