Devilish Tactic

Setting: Mother K is correcting her older son for being mean to his sister.

Mother: Did you say sorry to your sister?  

Son: (silence) 

Mother: Did you say sorry? 

Son: (folding his ears closed with his hands) uh oh, mommy, I can't hear you. My ears are not working 

Mother: What??  okay, fine, your sister and I are going to get some ice cream but I guess you can't come because you can't hear us.

Son: Mommy, I can hear you now
