Wood.

Removing that splinter gave me grey hairs.
Not one of those under-the-nail-shitters either.
No, this was an honest little nub,
Buried deep in my index finger,
Head on.

Safety pin digging revealed,
Sweaty back,
Well focused eyes, oh, so stressing.

Feeling well prepared to remove a tooth,
That wood may have replaced a nerve,
And instead I pulled that.
Long enough,
It probably touched my soul.

Ugh, souls.
I meant my bones.
