lightup shoes

--Mom bought YY and DD lightup shoes. YY just kept her light up shoes in her bedroom after the first couple of days of wearing outside. She said, Mommy, see, if i get up, i can see everything with my shoes here because  my shoes can light up. She used this as an excuse exactly when the other evening mommy complained she needed a clean up in her bedroom as mommy saying "YY, sth. on the floor will trip you if you get up during midnight" . " no mommy, my shoes can light up so i can see them". Actually YY is a good sleeper and rarely get up during midnight.
--DD just learned some numbers. So he always likes arguing with mommy by arguing back with a different number.
  Mom--- DD, you need a time out of 2 minutes.
  DD---- No, 3 minutes.
