Revolting

I find negative, toxic people revolting. No other way to explain that.
We attended a party which came after a few days of bullying and then to watch how such small children can be so unkind to each other which is clearly learnt behaviour made me despair. How can you combat that when trying to guide little ones??
I came home to pjs and warm socks and broke dry January with a glass of wine to ponder what to do next.
