*Kurt's Tip*
Respect. It's a small word with a lot of meaning. Respect what they do and say. When you respect someone, you listen, you interact, and you consider. (If that makes any sense, haha)

For ex: Say your daughter/son doesn't want to be bothered. You just stay away and give them their privacy. Respect the fact that they don't want to be bothered. It's simple.
