The pros: much less work on my part, no weather worries (ha)
The cons: many kids are out of town
So it'll be small but hopefully sweet. I have games and crafts planned, and they'll get to do water balloons and have fruit-sicles -- and hopefully just run around in the sun. For gifts, I asked all the kids to bring a gift-wrapped book, and we'll do a gift exchange (probably similar to a white elephant thing), so everyone gets a book to take home.
I have to admit, planning and doing stuff like this appeals to my teacher nature -- but I'm glad that this will be outdoors. Last year's party (for D) was in our house (it was rainy), and the noise level got to be a bit much!
So happy party day, all!
