Tear down the wall between your feelings and your words. Set limits and boundaries and communicate them. Make sure everyone knows what they are getting into. Learn how to defuse arguments. If necessary, learn how and when to say goodbye.
Actions communicate better than words.
Show people that you love them. Share kindness and affection and laughter. When in doubt, rub their feet. Having tools isn't enough, you have to really want to use them. Ya gotta wanna.
