I would think that children can only benefit from seeing their parents have fun and pursue things they love just for the sheer sake of enjoying themselves. Most people I know who had parents that gave themselves permission to enjoy life, really appreciate that and treasure it. Yes, they need to know that the grown-ups in charge will take care of them, and of what needs to be done. But it's a good thing to also observe that being an adult isn't always about mundane, everyday responsibilities. Makes growing up a much more palatable goal, methinks.
The world opens up... when you do.
Oh, oh, can't you see? Love is the drug for me. ~Bryan Ferry
