I think in a way you're doomed once you can envision something. You're sort of doomed to make it happen. I've found that the moment I can envision leaving a relationship that's usually the moment that the relationship starts to fall apart.
My kids love it. I thought I was the coolest dad in the world when I got to be in a Bond film but 'Harry Potter' too? Well I think I qualify for a medal for exceptional parenting or something don't you?
