C and I were walking on a beach, maybe with some other people. There were beautiful shells here and there, huge shells, in perfect condition. Some of them were quite vivid, excessive even. I picked one up and saw that it had what looked like gemstones set into its surface in a pattern. But then someone told me I couldn't keep it, because the whole beach was a preserve or something. I pointed out that the tides were going to drag these beautiful shells out and destroy them soon, that by picking it up I was actually saving it from destruction, but they said it was illegal and someone would stop me as we left the beach if I tried to bring it.
