I am not sure how anyone can label these memories as good memories. I was from Little Angel's and heard that a twin named Luv and Kus were the main ones getting into gang fights. Apparently one of them had a hammer nailed into his head.
Beating up people and causing harm can in no way be good. Now that we have grown up and can look back to our stupidity or simply cruelty, we should recognize them as such and not label our childhood memories as being good. Put yourselves into those who were beaten up badly or even stabbed and changed their life and that of their parents forever.
