When I was taking a kids confirmation class once, I began it by teaching about 'wow moments' as times when God is (probably) present - when life seems to hang together with sense and energy and all the lights switch on.
Via BBA I discovered one: "played 'heroes' in my living room with david bowie"
which I'm sure was a wow moment for Moby.
It'd be a wow moment for me.
I'm not sure I've ever had a wow moment quite on that scale. I wonder what it would be.
Possibly: giving a Peak Oil presentation to the senior bishops of the Church of England (half of whom know me already). That would be a wow moment.
Not an unrealistic ambition either (grin).
