Garden of roses

I was walking in a forest
It is beautiful but my head was in the clouds
I really wasnt paying attention...just walking
Suddenly i see the familiar iron gate
I was there. In the garden of roses
Inside there are a lot of red roses
The garden, it has a story
The roses were once white, not red
How they became red?
Beacuse of my blood
I was killed and my blood was used to paint the roses red
