Stranger

Do you know me?
It's been so long.
I can spell your emotions backwards and forth,
but could you pen my name down without getting it wrong?

Age is just a number,
I don't mind that you've forgot.
I worry though,
about your health, and that brain that seems to have gone to rot.

Don't you fret about me,
though I appreciate your concern.
For so long as you may be alive,
I shall make my home in your peripheral vision.
