things my children have argued about today

• the colors of the imaginary signs in our kitchen that say "clean the wood" and "don't clean the wood"
  
• whether nana, who works at their imaginary company named lampy, is the big sister of lala, who also works at lampy (and yes, lampy makes lamps)
  
• who is 2-1/2 and who is 4-1/2 (a reprise of an old standard)
