When the children were little we used Johnson’s shampoo. We got a bottle with a pump in Brussels and it followed us home and we re-filled it for years. It lost its label but the bottle was robust and it lasted and lasted.
It was in the corner of the shower for ages, almost empty, the children having long since moved on to more potent shampoos. I was in the shower the other morning and I noticed it was gone. I am normally ruthless about chucking things out and not engaging in nostalgia (a reaction, I suspect, to the attic groaning with old school books and the like in my parents’ house) but I must say, I felt sad about the plastic bottle. However, I suppose it will live forever in landfill. Not as comforting a thought as you might think.
