"What people say or do to you is a reflection of themselves, not you." This is what I tell my 8yo gal when she comes back to home from school, grumbling how some of her classmates are rude, physical, mean, etc. We can't control the world, but we can control how we react. Recently, I'm teaching her to learn to fight off negative thoughts and intention. The kids of ours will grow up in a complex world because of the social medias, we need to advance with them. You too 加油!
