That is a beautiful quote Chuck! I don't remember it from that show although I always liked watching "Little House"
I remember the episode very well.
A widow dies, leaving her three young children behind. Mr. Edwards and his girlfriend are watching them until they can be adopted.
When two couples are found Mr. Edwards doesn't want to split the children up, so he says he and his girlfriend will take them in, and to make the family "proper", he proposes to her.
