Keepin' ya grounded

The kids are in Brent's room playing and I hear Ryleigh start singing...next thing I hear is Brent saying, "Will you PLEASE stop singing!" There is a pause where neither one of them says anything (I can only imagine the looks) and then B says, "I'm sorry, but you are just NOT that good.." What are big brothers for if not to tell ya like it is?!?!
