I hate book fairs at daycare/school.
It seems terrible to complain about books, because obviously you want your kids to read. But I just hate the way these things are set up. It's always in a really obvious place, where they are completely unavoidable in case you don't want to buy your kid a book. Then your kid cries and screams every day because you don't want to overpay for some book that they could get the library.
Book orders are new to me and I find them equally annoying. Every month, my daughter comes home with the book order and begs me to get her books. Some of the books are actually really great deals and I would be happy to get her those. But those aren't the one she wants. She wants the stuff on the book order that are practically toys, like the sticker books or the fancy diary. And if I don't buy those things for her, she feels left out when the books arrive.
