Our Adolescent

Somehow we have a teenager living in our house lately. I'm not exactly sure how it happened--either he decided the headphones were a good idea because his baby brother was screaming and he couldn't hear his music or he didn't want the music to be too loud for his baby brother. Either way, Matt rocks out to his jambox while holding the earpieces of the headphones up against his ears but not in them. He does this a lot. We're wondering if we should worry about his hearing with the loud volumes that he likes to explore. He doesn't hear us already as it is. Or is that selective Jones hearing??
