Oi.. well, I can't give an exhaustive list as it would never end. But the big things I guess. I vandalized a golf course when I was 14. It was a horribly stupid move, brought on by my people-pleasing. I learned a lot of lessons from it, though. Then other things. Well, I've banged two married women, and many who were engaged at the time. For a while in college I had a reputation as a good 'last ride' before the wedding aisle. Not too proud of that.
But without question, the worst thing I've ever done is purposefully destroy a woman. I wrecked her through and through. Definitely going to spend some time in Hell for that one. I have my excuses, (she was married to my best friend and cheating on him, I didn't want his children to be raised by her, she was taking advantage of me, etc.) which are true, but ultimately, they are just excuses. The Queen of Heaven knows better.
Oh, and I started smoking. I regret that everyday.
