DeeDee249,
The difference might explain why JonBenet was missing underwear, then again you would expect to find a wednesday pair in the washing basket, or on her floor etc. Also if as you suggest Wet is wet and Patsy is resigned to JonBenet wetting the bed, so allows her to continue wearing her underwear, then why should she become so enraged when she does wet the bed?
Does anyone know if JonBenet actually had on a proper size 6 pair of Bloomies panties on Christmas Day? I can't remember if Patsy was asked this or not.
