*blinks in disbelief*
As a parent, you sometimes wonder if they're ever going to "get it". Then when they do, it's a surprise. I don't think I have low expectations, it's just the just the random timing and the uncertainty about what the trigger is/will be that produces the surprise. Maybe startled is a better choice of words. I'm not surprised, since I've been sowing since they were little; it's nice to reap for a change.
Congrats to you and yours orthodoc.
