She's a surprisingly good mom, all things considered. Her youngest's autism diagnosis was a blessing in disguise--she had to suddenly start behaving herself when it became clear that he was struggling. She met her fiance around the same time and he's a very good guy (we joke that he's a "lite" version of my DH). It's the rest of her family who ends up receiving the brunt of her bad behavior.
