I wonder sometimes at their resilience and ability to trust. From stories I've read and videos I've seen of adoptive parents that have already walked that path and successfully arrived on the doorstep of "gotcha day" and past it to going home ... these amazing little children have the ability to handle so much change and upheaval. And they learn to love and trust in such a short space of time (mostly).
This video is particularly touching as the adoptive parents video the first meeting and their daughter's adverse (at first) reaction to them.
