Consider these thoughts from my stream of consciousness:
It is easier to hurt children than to bless them.
Children are keen observers but poor interpreters.
You never stop loving people you have loved. Even when you hate people, you really love them. If you didn't care about them, they couldn't hurt you.
Gratitude is not getting something new. It is valuing what you already have.
Most of what you need to know about what is right and wrong you already know. Just listen to your gut.
If you are going to give advice, be indifferent about whether people take it or not.
