I Love Vocaloid

So my friend is playing some Miku music for me such as World is Mine (which I know all the lyrics to). Then, plays Po Pi Po and I start bouncing on the bed and sing the weeeee part and go crazy. Her mother suddenly opens the door midway through and sees me with a wild grin bobbing my head side to side and clapping. She says "Ooo-kay.."

When she replays it after her mom leaves I almost fall off the bed and headbutt the lamp, potentially knocking it over.
