who are you?

How do you sign your letters?

Yours Truly,

I have always ended my letters like this:

not sure who I copied this from years and years ago
the summer I was fifteen
my head most likely buried in library books
of some famous person to another
but I did and it has become more than a signature
it's my signature
like a familiar perfume pulling your head across a crowded room
or quirky fashion choices that reverb in tiny taverns

it's me.
