"A love letter for Princess Celestia." A mailpony announced.
"Oooh!" Luna giggled slyly. Celestia glared at her younger sister. She levitated the letter over to her and broke the seal magically. She slipped the letter out and started reading, her horn and the letter encased with a sandy yellow glow. "huh...ok...I see...very well." She murmured. Luna watched with rapt attention as the princess of the sun placed the letter on the table.
"Well?..." She prompted with a grin.
Celestia hesitated, then said -holding back her shock and excitement: "Somepony wants to meet me behind the Ponyville Library. It was signed: your secret admirer."
Luna practically keeled over when her sister said those words.
"Hahahahahaha... I got you sister!"
Celestia's face was priceless. The princess of the night continued laughing.
