Learning to Love

When I met you, I saw the light.
You made me happy everyday,
and you brought me back to the world and what a sight.
For you keep the darkness at bay.

Now you say that you love me,
you say I'm your happiness.
Ever since I gave you the key,
I feel like now I live my life and stop being just a witness.

You say "I love you" but I don't know if I could say it back,
truth is I don't know what love is.
My whole life I've been surrounded by black,
so this feels like a quiz.

I don't know what love is so maybe you could show me,
and maybe one day I can say it as easy as abc.
