A work colleague assumed our f/a son's biodad was a high school drop out and that part of his plan would be getting a GED. In fact he went to college! And people can be great parents without a GED, anyway!
MIL has repeatedly said "I don't know how anybody could give up a cute baby like that" as if it would be at all appropriate for a biomom to make the decision about whether she could successfully parent based on how cute her baby is?!
Even scarier--she is a foster parent herself! Her teen foster daughters are beautiful, and get great grades, too. Does she sit around them saying "I can't believe your mom didn't want cute girls like you!"
Also, she locks them in the house at night because she thinks it is in their blood to "run the streets". OMG.
You can train people, but you can't make them think!
