I'm insane

To me you're a rose
With the steam of a single thorn
And you can't just leave me alone to morn

Because the only part of you I wanted to touch made me bleed
And as I watch the bush you get lost in
You're the only flower I see
With your single thorn
To this day
I morn
Because that thorn is a part of me

Because insanity
Is doing the same thing
Expecting different results
And everytime I bleed
**I expect it to be green
