Speed of Sound

Jesse clearly has trouble with his hearing since, ya know, we have to tell him like ten times to go put on his pajamas and yet thirty minutes later he’s still just finally getting around to taking his socks off.  Yet somehow that boy’s ears can hone in on the precise frequency of a Mellow Yellow bottle opening on the other side of the house and it sets him off running: “Daddy, c’I haf some SO-DA???”  Wonder if that’s some kind of selective X-Man superpower?
