Dear dad, a series of letters written, but never sent

"Momma where's daddy?"
I've been asking her the same question,
for 15 years now,
he left when I was 3,
a single mother,
and her only child,
when I was 3 my mom was 17,
living off of dad and,
a minimum wage job,
kicked out,
by her own parents,
every other week,
I would write my dad a letter,
but I could never send it,
not knowing if he was at a bar,
or 6 feet under,
these are the things they don't see...
