Shell-like

Like my aging hairline, springs ice slowly recedes. Unlike my hairline, the receding ice reveals treasures hidden for many months.
I see things laying about and wonder how they came to be there. The shell is very tiny and may have been on a child's bracelet or necklace.
Was it a sad day when the shell was missed?
I hope not. I hope that the child thought it was time for the shell to move on to someone else.
