I don’t think it’s weird at all. Being attached to physical objects is a totally normal part of being human. The comfort of familiarity is natural and nothing to be worried about. The personal example I can think of right away is that when a wallet wears out and I transfer my driver’s license etc to a new one, I’m aware of the same feeling of attachment. Throwing out the old one feels like a betrayal. I think feelings like that are completely natural. In fact my childhood cuddle toy - a stuffed dog named “Poody” is still up on a bookshelf over my desk. I hardly ever think about him but he’s always up there, kind of watching over me.
