I told her I knew nothing could happen now but my son was injured and in the future they should pay attention to the weight differences. She said that with Heavyweights they do not know the wrestlers weight in advance, so she would not have known there was a weight difference. I tried to explain to her there was a 150# class and a 170# class in 10 and under. I tried to explain that they would know the exact weights at weigh ins and with trackwrestling the brackets could easily be changed prior to the start of the tournament. That is when she said she did not want to discuss it further. I was very calm.
