My sister has two very tall teenagers, a dog, and a partner. According to my sister her kids are always complaining that the car is "too small". She on the other hand thinks otherwise. She has a five seater car. She lives in the UK so the car she has isn't all that spacious. I think technically it's a 4 seater as the middle seat in the second row is half the size of the seats beside it so only her dog can fit on that, hardly, and is squashed up against her kids. Her autistic daughter is very sensitive to her dog, and it makes her daughter have meltdowns, yet my sister won't get rid of the dog despite. One of my sisters kids have autism and require about as many things as a baby does if not more. My sisters kids have barely any room to put their things let alone move their limbs and it's very compact and uncomfortable for them. They live in a rural area so they travel for hours at a time to get anywhere. I told my sister I think she's being unreasonable having such a small car based on the size of her kids and the amount of things she needs to haul. She said she doesn't like big cars and therefore isn't getting one. Aibu to think she's being unreasonable for this?
