When this aunt is frustrated with her brother and his kids, she asks Reddit:
So I will begin by saying that I (F28) am on the spectrum. I don't really like children and I definitely do not plan on having any. I own my own house and I allow my parents to live in my basement. It is a fully developed suite not a dungeon.
I have an office in my home. I keep boxes of brand new Lego in my office. Building the kits helps me relax. Afterwards I keep the minifigs and I donate the pieces and plans to a woman's shelter so the kids have something to play with.
My brother, his wife, and my niece and nephew have come for a visit and my parents asked me to let them stay with me upstairs so they weren't so crowded. So I said that my brother and sister in law could but that the kids should stay downstairs.
