Yes, I talk to my kids when something is bothering them. But sometimes they need to deal with it in their own way. They don't want to go out, they don't want to talk, they don't want to play a game. They need to veg. Why is vegging wrong? Nobody's advocating letting a kid sit in front of the TV for a month and not talking to them. I'd bring my kid food, snacks, ice cream, give them backrubs, etc. In short, I'd give them what they need, which is freedom from coersion (Turn off that stupid TV and go outside and play!), space (let them know I'm there if they need me but let them be) and trust.
And sometimes, when I'm working things out, I need to be alone to think and not be bothered by people yakking at me trying to 'help' me. Help is offered, yes. But I can choose to say thanks, but I need my space right now. And I allow my kids that same choice.
