Bullying is not new... I went through it myself 30 years ago and I'm sure most everyone on this forum has experienced it or is still experiencing it. The biggest factor in trying to control it is to speak up. If you are being bullied, or see someone being bullied, tell an adult.
The story even states that the boy mentioned something to his father about being bullied, but then the next day told his dad never mind, we are friends now. What made him change is mind is hard to say, but my guess was fear of retaliation.
Very unfortunate that his life had to end... it sounds like he was one of the good guys and had a bright future ahead.
