Bosses didn't condemn on my mistake. My boss just kidded on my mistake and said (in a very funny tone), "對唔住?!打張memo解釋先再講", "你地死梗喇, 睇下你地以後仲敢唔敢求求其" He and other teammates thought this mistake was not easy to be avoided. There was solution to solve the problem. And the senior bosses won't get to know the matter. Another boss said nothing to me, just shook his head (with smile) when he saw me. Actually, he never gets angry even we have done something wrong in the past. He just always showes smile on his face and we won't know what he is thinking all the time.
Some other colleagues (of other teams) said it was not a big deal as I am going to leave. They didn't know what mistake I have made but they may get to know later.
