Having had one child in each category, I always found the quietly sobbing child more heartbreaking. And I have done my share of peeking though the window after the more spectacular drop offs.

Getting back to the looks from other parents, I always look, but I am trying to channel a supportive, "been there done that, what can you do?" vibe. I think your life might be easier assuming that's what other parents are trying to communicate, if only for your own sanity. Also because the tenser the parent get the more wound up the kid ends up (yep, it is always the mom's fault! can't win that game!!).
