City of lights

Looking down the hill many I see.
I see buildings lights and trees
I see many lights shining bright,
I see lovers hugging under the light,
I see cars and buses everywhere,
I see traffic lights from green to red,
I see people laughing people frown,
I see kids running all around,
I see drunk old folks singing out loud,
I see young people in a crowd,

But you weren't inside the frame
Why is that? I yelled your name
but I only heard echoes of myself
Around me there is no one else
Then I finally realized
You finally walked out of my life.
