Perking up with percussion

Yesterday Sierra waltzed into the kitchen right after breakfast with a maraca in one hand and a tambourine in the other. I was just taking Evi out of her seat at the table and as soon as she laid eyes on Sierra and heard the commotion, she just started laughing out loud. She just kept laughing and laughing, and when Sierra handed her the maraca, she laughed about twice as loud and kept it up for probably 2 or 3 minutes straight. It was really the funniest thing ever, and by the end of it, Evi, Sierra and I were just rolling around the living room floor in stitches!
