I simply can't imagine how much harder it is to be a young child today, let alone dealing with bullying. You're already coping with the relentless pressures of constant testing at school, homework from a young age, the sometime insidious effects of all-pervading social media and the internet, plus fearful parents who rarely let you play outside.
What has happened in Paris and in Beirut recently is a very shocking and terrible thing and how you talk to your children about it will vary a lot depending on the age of your children and their temperament and your own values. While everyone will be appalled by what has happened there may be different aspects of it that you would want to highlight to your children.
I hope that by sharing my story and helping prompt the start of a conversation about bullying, other people may feel empowered to share their own story or make an effort to not turn a blind eye to bullying. One of the greatest maintaining factors of silence, making others aware of what's going on and seeking support can enable individuals to get through being bullied.
