They were in charge of decorations (drawing pictures on the plastic tablecloth):
They were also in charge of food prep (dipping pretzel sticks in white chocolate and sprinkles):
They were in charge of recreation management (they did a lot of shrieking with glee and laughter!):
They sang Happy Birthday to Naomi (a bit early for that, but she was thrilled), played Valentine's themed bingo, and ran around the house shrieking some more.
They neglected clean-up duty...apparently they thought they were guests, not the work crew!
