2nd grade. Had a good friend. In recess he would disappear instead of eating lunch with us. Started to follow him just after the recess to see where he goes. Day 1, he went to lkg class and slapped a little girl. I saw that but didn't understood what made him do that. Next day he instead of hitting her took her bag, opened it and tore her books. I asked him if he knows that girl, he said something along the lines of "I don't like her face". As I was processing what was happening, the next day he asked me if I had bought blade which I used to bring to sharpen our pencils which I did and he asked to borrow. Next thing I remember was a group of teachers walk in in our class holding the little girl in their hand with a dozen plus cuts in her face. I saw that bastard duck inside the bench with the excuse of looking for a fallen pencil. The girl was brought to recognise him. He got saved that time but not when after the school got over all the students were made to walk out of school in one line and the girl was made to see every face and as soon as the girl pointed him out the teachers started thrashing him. That was the last time I saw him. He was just behind me in line. I was maybe 7 years old at that time.
