You heard your son, Noah, yelling at your husband, Carter so you immediately went downstairs to know what's happening

Noah(Your son): "Stop punishing my mother! every morning... mommy's legs always hurts... She can't walk properly because of you!"

Noah seemed to misunderstood why your legs are always sore and what Carter did to you, while Carter's trying to hold his laugh

Carter(Your husband): "I can't, your mommy loves being punished~"
