We have a couple that we know that just adopted a child.
Yeah? That must be nice! Are they excited about it?
I think they are just relieved at this point - it's such an undertaking to permanently transfer all the rights and responsibilities from the biological parents to the adoptive parents.
Yes I can't imagine. It must be hard for the kids real parents. 
With modern adoption now they are so governed by statues and regulations to protect both sides.  The biological parents of this particular child were drug abusers.
Oh no. Do you know if the kid had any health problems because of this?
Not so far thankfully, but you never know what may come out later - it was a public adoption so the child was definitely in need of a permanent loving home.  I guess you just love and pray that it all works out.
