The Princess and my niece were hopping through the house (LOUDLY ... hop, hop, hop, hop, hop, hop, HOP, HOP, HOP!).
I yelled from my room, "Please don't run through the house."
They hopped right up to me and the Princess said, "We're not running - we're hopping," with a big ole' look-how-good-I-can-hop, smile on her face; still hopping, but now in place.
I said, "Even worse - stop the hopping!" and they hopped on out of my room.
