I have posted about this before under several different usernames. It always flares up at Christmas, but happens throughout the year to a lesser extent. Ex MIL is a hoarder. She sends us a lot of her hoarded junk, at every opportunity, especially Christmas. I have asked her multiple times, and in as kind a way as possible, to please stop. She spoke to me months ago about a stack of books she wanted to send for Christmas. I asked her not to. One was a book I already own. I told her this. She has sent it anyway. One book is for dd and quite inappropriate for her age. Ex MIL warned me before sending and I asked her not to send it. She sent it anyway.
AIBU (or ungrateful) to dump them at the nearest charity shop? I am fed up with the boxes and boxes of old junk and second hand clothes she keeps sending (that she finds on eBay and in charity shops). She doesn’t have much money, but what she does have she spends on “bargains” that she either hoards or sends to us. She calls me rude and ungrateful when I ask her to stop sending us her junk. So far this month she had sent 5 small boxes of ornaments, a big bag of clothes and the 6 books.
The last time I posted about this the advice was to give it all to my ex to deal with. I have been doing this, but the kids still end up with it and it works its way back to our house.
