Some people attach more emotional value to items like that. Some don't. I did for a long time. After a lot of big changes I kind of stopped hording things as much and it was very freeing.
I used to never ever get rid of gifts, even if I no longer had any use for them and they were just contributing to clutter. It seemed so ungrateful.
Then I had to get rid of a lot of stuff during a very fraught move, and I thought: someone gave me this because they love me and want me to be happy. Would that person want me to obsessively, guiltily cling to something that doesn't benefit me anymore? No. They'd want me to get rid of it.
