I've found that the answers we find ourselves are the most satisfying. Doesn't mean we can't enjoy some help along the way though and so, if you'll forgive the dreaded question being answered by another question, I'll give it a shot. You said, "I'm not judging them... I don't know what's going on in their life or how they developed or anything, I'm just coming from a place of curiosity..."

So, out of curiousity, what would have to be going on in your life, or how you would have to have had developed, to do the same thing? You are more engaged with the world when you...? You are less engaged in the world when you...?
