It is sad that bullying goes on as it does for no reason except there are bullies.
My 2 grand daughters that live close to me were both bullied. The oldest because she is tall and slender and smart. The youngest is what they call high functioning autistic. There were 2 girls at their school last year that would pick on them every day. My oldest eve got sent to the office because she stuck up for her sister when one of these girls was pushing her around. Now my son and DIL went to the school and complained but come to find out, the 2 girls causing the problems were the assistant principals kids so nothing was done.
My son called me one day and asked if I would mind riding over with him to pick the girls up after school on our motorcycles. Sure, I'm always up for a ride. The first day we went, our kids came out and sure enough they were being followed by the 2 brats and of course they were at that point verbally picking on them. Now we were parked right up front, 2 large (both 6'4 and 220+ lbs) men in leather vests (S & C and AF & AM on the back) and our girls came up. we gave them their helmets, the put them on and climbed on the bikes. The look on the 2 bullies faces were priceless as well as the other kids watching.
This went on for a couple of weeks until I had to go out of town. Come to find out, they had just become the coolest girls in school and no one would let the 2 bullies get close to them after that.
