The Birthday Boy

I'm neither your friend nor your enemy.

I'm neither your lover nor your hater.
I'm neither your sister nor your stranger.

But..
I just know you.
And you often see me.

Thus, I think..
I need to tell you happy birthday.
Happy birthday!
I need to warn you.
You've been 20 now!
I need to wish you some good things.
I hope you have a better life.

And I wonder..
What would you respond?
Thank you.
or
Who are you?



*p.s. Er hat heute Geburtstag. Alles Gute!*
