Accept her offer

"Fair lady, it would be my honor to have this dance with you" you accept her hand and gently guide her to the dance floor, joining the rest for the start of the next song.

You two fluidly glide through the center of the dance floor with everyone quickly glancing your way. She danced masterfully, easily compensating for your amateur missteps. She smiles confidently, knowing how impressive her skill is. When the song was over, you two split ways and the next oldest sister came up. This continued on as they went down the list ordered by rank until all twenty have danced with you. After that, the ball was concluded.
