One of my favorite poems of all time. The best thing about it, is that I know the person that wrote it.

so much time wasted on nothing
so many bridges burned
even though ive been here before
i didnt pay attention to those lessons learned

i get left with nothing but memories
well you leave with your head up high
i cant stand you and all of your kind

they say history repeats itself
and it always repeats shit on me
they say you learn from your mistakes
and i havent learned a damned thing.
