Missing without Meeting

It's seems like an oxymoron,
but I promise you, it's not,
to never have known someone
yet never to have forgot.

Our relationship lacks introduction.
It lacks sight, but never love.
I only know a first and last name,
but we've still got the same blood.

It seems so strange to miss
who you've never met before.
But find out about a brother, I guarantee
you'll love 'em even more.

Everyone says it's crazy,
impossible to happen in this age,
but I believe I love you, Devin,
so Bubba, happy birthday.
