I do do this, sometimes without even knowing I'm doing it
I tend to feel bad about people giving away objects, so when they don't need them anymore and have no use for them, they can give them to me
seriously I have hair bands, empty bottles, old broken phones, a couple of magnets, a vape, random letters that people didn't tear up, a box of someone's fake nails, a few sets of keys belonging to... well, who knows- old places they moved out of probably, loads more- all from other people that don't want them
also if I see someone with something I don't have, then I need to hoard it
not their's, but I need to get loads of them
