My nephew is nine. I have bought for him, amongst other things, a boxset of the Diary of a Wimpy Kid books. My sister asked and I told her what I got him.
She has now gone on a rant, saying the books are inappropriate for his age. When you google, the stated age range is 8-12. I read them at age 10, and loved them. She says that because they mention "butts" and kissing, and she says it's stuff she doesn't want him to know about yet. She's actually, genuinely angry about it.
AIBU to tell her that if this is how she will be, I'll send it all back?
If she had just said "thank you for the thought, but we think he's a little young for that", I would not care in the slightest. It's the sheer anger that has me thinking that I can't be bothered to deal with it.
