Excellent judge of character?

... or too trusting for her mother's cardiac health?  The Chief and I sat across from a woman and her 2 little ones on the rental car shuttle on our way to the family graduations.  The 4-year-old, all curls & big eyes, was very chatty, which of course the Chief loved.  He didn't get to chat with her long, though, as it's only about a 5-minute ride.  Saturday afternoon, as I was waiting in line to board and the Chief was off searching for a restroom,  I spotted a familiar family.  Little Miss Curly-locks obviously recognized me, as she lit up and ran at me full tilt with her arms open wide for a hug!  Naturally, I couldn't disappoint the dear thing, though I quickly released her, not wanting to make her mother nervous.  The poor woman smiled a bit sheepishly and said "She's very friendly!"  I commented that the girl obviously recognized me from the rental car shuttle the week before, hoping to reassure Mom a little that I wasn't a complete stranger to her little girl.  That's a tough balancing act - you don't want your kids to be afraid to talk to people, but you don't want them to be too trusting, either.
