There is just so much stuff, multiples of everything, at least a hundred Tupperware containers in the kitchen.
My mom grew up rather poor, and I've talked to her about her borderline hoarder tendencies. She says it's an unconscious thing, stemming from when her family couldn't afford to buy new things, so they saved everything that could possibly be repaired or repurposed, and she falls into a tendency to still do the same thing. Over 24 years living in that house, it just kept accumulating. It's not like it's a mess, mostly everything is nicely organized, there's just a lot on every shelf and in every drawer stuffed to the brim.
I fell into the same pattern for a while, keeping extras around of a bunch of things for no real reason, combined with being very bad at throwing things out or giving them away. I've gotten better, but it's a constant thing.
If you like cooking, wouldn't a kitchen be important to you?
What if you do woodworking, or you work on motorcycles in your free time? Then does a garage make sense?
