I'm a boy mom

A couple weeks ago in California Kade fell at the tide pools. His hand bled a lot and he swore a shell or rock went into his hand. I couldn't see one. Today he told me it was still hurting. I looked at it, it was hard and had black in it. So I disinfected tweezers and cut it open and out popped a tiny snail shell. So weird and gross but he's so proud of it. He's such a boy.
