I don’t know. I have lost touch with him since 1997. Obviously I can recognize him by face but all I know is that his name is Zubair Siddiqui (Arain Caste), his father passed away when he was young, and he used to live in Punjab (Khaan-e-Waal City) and then moved to Karachi.
The good thing is that you realized your mistakes and have apologized to those people, that’s what really matters.
You are right, one should not hold on to the mistakes of past, but we can learn from the mistakes that we made and that can help us NOT make the same mistake again. I learned from these mistakes to be more mature and always stay calm. I learned that I shouldn’t jump to conclusions and should always think about the situation with calm mind.
