His teacher told them that they can exchange cards if they want to, but they don't have to. He chose not to do it... 
They can't call it a party because they're only allowed 2 per year. They've found a loophole so they can have a party without calling it a party.
They're calling it a card exchange with snacks.
), my dd almost got the Harry Potter and my ds almost got the Scooby. But I told them to hold off and wait to see if they had more to choose from. My dd was so glad she waited. She loves those annoying twins.
I don't know why my ds changed his mind. I think it's because he knew I liked the Scooby cards better.
Should be fun.

I already have visions of the sugar high!
Actually, I did it last year and it was fun...exhausting, but fun.
