The balcony skinny dip that got witnessed

It was 2am. We were in a private balcony. The hot tub had been closed for the night and we really wanted to feel the ocean air. My partner suggested we use the outdoor shower on the balcony au naturel since nobody could possibly see us. We were wrong. The cabin directly above us had an overhanging balcony at a slight angle, and the person up there was also an insomniac enjoying the night air. We made direct eye contact at the worst possible moment. They very slowly raised their wine glass in a toast, turned around, and went back inside. We never saw them again. We skipped the formal dinner the next night out of pure paranoia. The ocean air was worth it though.
