Gone Unnoticed

The feeling of being in invisible and not being seen by the ones you want to notice.

See Me?
Of course not
I'm a grain of sand, in your perfect ocean.
I'm a gray cloud, diluting your deep blue sky.
I'm just an irritation,
A bothersome fly,
always distracting you.
Am I but a flea on a dog?
I guess you'll never know me.
Only because you don't see me.
For I go unnoticed.
