Dear parent of my kid's friend,
I know my kid is partly to blame here. But sometimes eight year olds don't know better and the adults have to be the smart people in the room.
When our kid came over for a playdate, for the love of God (and I capitalize God for your benefit, since you seem to want everyone to know how important your Faith is), please don't give her unlimited, unsupervised access to all of your Costo garbage treats and girl scout cookies. The next 12 hours after her departure from your house didn't go well for her, poor thing.
Cheers and God Bless,
Space
