I don't know...If I moved out of town I could easily bring one of my girlfriends with me to visit my mom instead of my husband. And I could easily go out dancing with said girlfriend and leave my kids with my mom. I could also come home drunk of my ass (which never happens but it COULD), and my mom would NEVER think to pass judgement on me, compare me to what her mom would have called 'sluts', question my respect for her, or even bring it up in a negative way. My mom would say "did you girls have a good time? It sure looks like it". She would never consider that I was being disrespectful, or abusing alcohol, or using her. She would just know I needed a night out.
But then again...I actually have a very good very close relationship with my mom.
