The most horrible thing I can recall me doing, is when I went lake tahoe to be the best man in my buddy's wedding and I missed the wedding and everything due to trying to win $10,000 at a blackjack table after starting with a mere $100.00 my buddy was so upset with me and with good reason that we stopped being friends for almost 4years
Note at the time you should know that took that $ 100.00 and turned into well over $8000.00 after graduating from playing$ 5.00 to$ 10.00 a hand to$ 100.00 a hand. I guess I was just caught up in the moment but to this day its the one thing that I have always regretted even if I didn't like his future wife.
Bully someone when I was young. (I am ashamed of it now).
Can't say until the statute of limitations runs out.
I said something really nasty in Spanish to this very nice Mexican girl in the ninth grade. I still feel bad and stupid about it.
