Tamarind Tragedy

I was in 4th standard when this happened. There used to be a big tamarind tree in the backyard of dilapidated building, just 2 buildings across my school. Most of the primary school boys visit this backyard after school hours to have raw tamarind. The boys used to come in groups and sometimes with their seniors. It was a big tree and these guys used to hit the raw tamarind with the stones. I used to go there with my friends and try my luck there. Even I tried throwing stones: It neither hit the target nor reached height of more than 6 feet whereas the lowest branch tamarinds were hanging were around 7 to 9 feet.
Once I went there alone. I found most of guys in my age group came with a senior who used to hit-and-get tamarinds for them. I felt left out. Don’t know what came over me suddenly, I picked up a big flat stone (imagining that I would hit a big bunch and show-off to them), took few steps back, ran few steps and with full energy took threw the stone at the tamarind.
Two things happened:
1. Certain things never change. Such a powerful throw did not change anything: It still did not hit the target and never reached height of 6 feet.
2. I expected the stone to hit target like a rocket, unfortunately (but expectedly) with the same force, took the path of projectile and landed in compound of the next building where few men were working!
"Aiyoooooooooooooooooooooooooooo!!!” came a loud cry and few people there started shouting. It had hit the working men, not the hanging tamarind!!

Next minute, I didn’t know what carried me- wind or legs- I was there in my rickshaw- hiding my face with my napkin, silent, shivering and sweating!
After that for next one month, I never stepped out of school after school hours!
