You once saw me

You once saw me, but now I'm dead,
I'm scared of what is yet to come,
For me, you have no tears to shed,
For I stuck out like a sore thumb.

You once saw me, but now I'm gone,
Swallowed by the pain of living,
Life is just going to cary on,
But, tis also unforgiving.

You once saw me, but now I'm not,
Not even just a memory,
No one remembers who I shot,
For I am just an emery.
