I am not a perfect man, I do have something I ashamed of, let me tell you one thing that I regreted.

I had a puppy once when I was still young, I adopted her since she was 3 month old for she was such beautiful and beloved, I can't stop just carrying her home, my parents were very angry about this because they think the puppy will make their life a mess! I was angry too because I wanted this puppy so much!

Turns out that my parents were right that the puppy was a disaster, she bits and broke lots of stuff, so I just abandoned her, now I got another dog and every time I look back in the past, I feel ashamed, because man should do everthing to protect what he loved, once he made the decision he should keep going and to make all things right.
