Funny you say that R18, I am a personal shopper.
And R30, in the middle of writing this thread, I almost stopped to change it to that exact same issue. I grew up in a cluttered house and it was traumatic. As far as traumas go, it's a very mild one. But it does have an effect on you. I was constantly embarrassed by my home and we didn't have people over. If someone came by, you never answered the door. When family would visit from out of town when I was a kid, I would spend days straightening up, cleaning, cutting the bushes, doing dishes, cleaning my room and my mom's room because I didn't want people to talk about her. She could never throw anything away and always felt the need to be surrounded by stuff. Even to this day, if she visits me, I could have enough storage space for everything she has brought, but her stuff still ends up on top of the dresser or in piles on the floor, clutter piles of receipts, cups, plates. The mismatched jumble of hangers was only a small part of it.
To this day, I only want clean surfaces, clean floors. If I have a couch it is raised up off of the floor so I can see the expanse of the clean surface under it. I want nothing extra than what I absolutely need. And I am constantly culling my belongings, getting rid of duplicates or items I don't need. The only thing I keep long term are photos, letters from family and greeting cards.
I've always wanted my mom to have a nice home. She just wasn't much of a home maker. That is what I have become, and I have tried to do it for her. We have had huge fights over throwing out things, getting rid of clutter in her small condo (that I actually bought for her). She only seems to think you get rid of things if they are broken, and every little thing is a future project. And she loves to shop for random, random shit. We had to ban her from Zullily in my home. She erupted into tears when I got rid of an old Nano that I got her like twelve years ago, that you couldn't even use anymore. I hate to make her cry, but I have to make her see. I don't dare call her a hoarder, it was never THAT bad, but she has all of the characteristics of a hoarder. Actually I did call her a hoarder and she collapsed on her bed in tears and wouldn't come out for a couple of hours. These types of relationships are always tough when you genuinely want the best for someone BUT you kind of have to let them be who they are. Letting them be who they are is sometimes the best thing you can do for them.
She did like the way I fixed up her home though. She always thought I thought her stuff was crap and I wanted to get rid of it. But I actually used all the things she already owned to interior design her little condo. I paired random knick-knacks she had together so they made sense, used throws she had bunched up in the closet. I actually hung pictures that were on the floor leaning up against the walls for years. She saw her stuff in a new light and liked it. I think I did finally break through. At least when I go back to visit her now, it's exactly the same as I left it, except for all the almost dead grocery store flowers she likes tending to and drying out.
