"Dear Dr Freedhoff,I reached out to him and asked if his granddaughter might want to write a short comment regarding her decision as well as send along a photo of her protest shirt.
Thought you would like to know that my granddaughter Frances (9) has refused to participate in a Cola-Cola dance which her school has arranged as part of some sports sponsorship thing, this without any prompting from me. She must have been reading your blog. She wants to wear a t shirt with "water " written on it."
"I did not want to be in the coca cola dance, because little children shouldn't be dancing in the favor of a soda company. Also my sports teacher shouldn't be encouraging small children to drink it. You need to stick to healthy foods like fruit,vegetables,meat,and occasionally oils and sweets.And for those public health folks who think partnerships of their organizations with the food industry are a-ok now you know that even some 9 year old kids perceive them as problematic conflicts on interest.
Granddad - I imagine you're darn proud of your granddaughter. Good on her!
