I have a friend, GREAT guy, one of the most genuinely nice people I've ever met.
His family has an old ass poodle. He was trying in vain to housetrain it and after a while just started getting frustrated. Well the poodle took a giant shit in the middle of his room, and he got frustrated, picked it up and tossed it off the front porch of his house (not THAT high off the ground, but still).
Well the poor poodle didnt manage to land right and it's now paralyzed behind the shoulders.
I felt really bad for my friend, that's a LOT to have on your conscience. He cried like a little girl for hours over it. There are so many assholes in the world that just dont care, and that happened to one of the nicest guys I've ever met. Kinda unfair, but I guess the real harsh thing about it, is that it is entirely his fault and he knows it.
