Burn like me

You were gasoline, And I was the lighter. Innocent at first, but then I sparked a fire. I had done this before, not just to you, but to many, Because I have always been burned, yet still none of you have listened. I left you scarred and wrinkled, Yet you brush it off like a cut or maybe even a splinter. Iv burned you like me, So why do you not understand? Maybe it's just me? This is something I can never ever understand.
