When I was a kid, my elder sister had went on a school trip, and she came back with a plastic bag filled with tiny shells. She told me that if I put a shell near me ear and listened to it, i’d hear the sound of the waves. I got so excited and told myself that I’d collect shells too when I grow up.
When we travelled to Morocco, we went to the beach and I found plenty of beautiful shells. I started collecting them and brought a handfull back with me home to Sweden.
Collecting shells is very calming, especially when listening to the sound of the waves in the background. But I’m not really sure if you can bring that sound home together with the shells. I guess it’s just a myth.
