When Arwen was young 7-9

Arwen looked for a place to dance naked where Galadriel wouldn't catch her and spank her again. She hoped to get out of range of her Aunt's mirror pool, so she wandered outside Lothlorien's magically protected borders. An orc caught her in the act.

The orc that interrupted Arwen's dancing was no match for her speed and her strong legs. But Galadriel saw this near-disaster in her mirror pool, and was determined to put her niece over her knee again.

Arwen's thoughts: "Oww! I hoped I was out of range of Aunt Galadriel's mirror pool, but she saw me dancing naked again. I beat that orc that tried to ravage me, didn't I? Ouch! Same lecture as my father gives me, about putting myself in danger. Yeow, she's spanking much harder than last time. I think she's using the mirror to see how much it's hurting me. Oww! And it's embarrassing having Uncle Celeborn watch. Elbereth knows what he's seeing back there!"

After this, Arwen was packed off back to her father in Rivendell, where she was destined to meet a young boy named Aragorn...
