Mom always remind Mary, 'When you're wearing the skirt, you
don't play on the swing or many people will see your
panties.'
One day, Mary happily returned home and told Mom, 'Mommy today I
competed with Tommy on the swing and won!'
Mom angrily said, 'Didn't Mommy tell you that when you are wearing
skirt, you shouldn't play on the swing or else the people can see
your panties?'
Mary proudly told her mom, 'But I'm clever! I took off my panties
so they can't see my panties!'
