There was a kid in elementary school years and years ago who bullied me and I simply took it. At the time I was too worried about getting in trouble to do anything about it. The thing I did not realize was at the time I was a lot stronger and a much better grappler than 99% of the boys there because of my brother who is 7 years older than me and I was used to taking him on.
It's strange thinking back on times I could have easily destroyed the bully.
