You could say that the happenings at Columbine were a result of bullying. Some kid, gets his (or her) giggles from picking on another kid. Most of the time we call it "being mean" and let it pass. Until that first kid, brings a gun into the school THEN it's finally noticed and labeled as "bullying".
Yesterday I had an incident with a co-worker. She's a known "Negative Nelly", constantly has to have everyone's attention, and does it by being the biggest pessimist in the department. When she doesn't get her attention that way, she's rude, inconsiderate, and well... mean. I already said it- but as adults we call it being a "Negative Nelly"... but really, she's just a bully.
Earlier this week, I overheard a coworker talking to his college daughter on the phone. I missed the entire conversation except when he told her to "be nice". right before he hung up the phone. I said, "you must have been talking to one of the kids", and he went on to explain that his daughter often speaks down to people when she needs help. She too- is a bully.
My wellness tip this week, is to really take notice of what is going on around you. Notice how your friends speak to others, how your boss speaks to you. Be mindful, that bullying isn't something that stops in high school. And watch your own actions- do you
