Karma is real shit...Or coincidence in my life. Do whatever you need to do to feel better.
But I grew with a best friend one time. He was like my bro. We lived together for awhile, did eveything together. Then the big mo fo harvested and told me we only got two pounds from 25 plants. I seen the plants the week before, they were 6 feet tall. There was definitely at least 10 pounds. Anyway, I started them all, bought everything we needed cause he didn't have a job and walked away with a bit of wet dope.
I let it go because I really loved his parents. And as the years go on his life gets more and more fucked. He has been busted with 22 pounds in his trunk, his girlfriend had a miscarriage, and he rolled a 2005 F-150 for which he only had PLPD insurance.
In the end, I am completely satisfied and have no regrets not doing anything to him. It may not be karma, but stupid people have whats coming to them and I'm sure there is more to come for him.
