To me its the types of stuff they keep that's the bigger problem, like I get finding it hard to do away with stuff that actually have sentimental value to you, maybe a certain stuffed toy or a dress that your kid wore for 3 years because it was so special to them an it reminds you of that time, or even gifts that were given for special occasions, I'd think those would naturally be hard to give away an naturally you do want to hold on to those memories if you have memories with them
But they must have 100 t-shirts J has never worn or even looked at because they bought shirts from every single little shop on one out of the many vacations they took, or what about the 30 reusable bottles, or the countless toys that were bought just to shut the kids up that don't get looked at, they don't have a house full of things that give them memories, they have a house full of tit that was bought spur of the moment because they needed to feel good at the time spending money
