I was a substitute teacher for about 4 years. Theres always a kid or 2 or 3 with no friends.....and theres usually a reason. Even the weird kids will find another weird friend or 2. The loners are usually disruptive, bullies, and sometimes just plain mean. There are kids who are bullied but they usually have a few friends.
Not sure what makes these shooters crack but its definitely a combination of things and just not as simple as this letter makes it seem.
It seems like the Florida shooter had some neurological issues if you look at his photo. I see fetal alcohol syndrome in his appearance. The one who shot Gabby Giffords was as mad as a hatter. Same with the Sandy Hook killer - whose insane mother gave him guns. (We’ll never know what happened there!) None of the lonely kids I went to school with ever ended up shooting up a school or mall. Something else going on here. Mental illness for a start.
I always let them come to my room during lunch so they’d have someone to talk to. Eventually, even the popular kids would come in for lunch.
