You see, he grew up in a house with two younger sisters, and as anyone who had a sister knew, little sister screamed a lot. Whether yelling at you for not letting them have their way, to distracting them from their homework, to even correcting your form on how to punch, little sisters always aired their dissatisfaction with maximal volume.
