You push open the door, the key turning with a soft click. The music is low but distinct, and you hear a soft giggle. "Hello?" you call out, confused. A moment later, your neighbor's older sister, Isla, appears in the hallway, a surprised look on her face. She's wearing a soft robe that barely conceals what's underneath, and her hair looks damp.

The air feels a little charged with the surprise of the encounter and the late hour. What do you do or say?
