Gone mining

Underground is where i live
because its where you fail to look when you search for me.
Beneath the earth. Thats where i dig my tunnel.
Like a creature of the earth...in the belly of the earth.
I heeded to run with my head low.
Till am ready to see how much ground i covered . Then i will shield my eyes and straighten up.
So next time you meet with ama and she wants to know which way i went.
Shrug and pass on by.
It is not yours to say.
But fret not on my tunnel
nor call out at its entrance
in it i find my minerals...underground is where the mines are
if we meet at the end of it, i will smile and mouth all the hellos i missed
so till then my friend
