I couldn’t find a meme that shows this, but I used to tell my children. Do onto others does NOT mean if they hurt you, you should hurt them. It means if you want them to be kind to you, you need to be kind to them. And if they are not kind to you, you should still be kind to them!!
I may be a “Pollyanna” but I think that if everyone would follow this one rule, things would be a lot better in this world.
