How old is old enough?

My mother, bless her 90 year old heart, still thinks her daughters are all still 16 and should be living by her rules. Especially when it comes to relationships. I was at her house today for our regular Sunday brunch/Canasta blow out event when one of my sisters brought up some tentative plans for this summer. She asked me if I was going to be involved in said plans and I told her that I wasn't sure since Alex was coming here for almost two months and I would have to wait and see.

My mom said, never looking up from her cards, "Almost two months?"
I said, "Yes, he's coming in June and staying for part of July and then I'm going back to Sweden for a while when he leaves."
My mom, still playing her hand, said, "Where will he sleep?"

Now, let me explain why that's funny. She knows full well that Alex and I have a relationship and he's been here for months at a time before and always stayed at my place which is a one bedroom apartment. So, she knows full well where he'll sleep. Haha! But, there is that something in her mommy voice that always renders me back to that 16 year old girl. And my response to her was, "In my apartment..."

Thus is the relationship my sisters and I have with our mother. We are well over the age of reason and half of us have stepped into the age of no return but we can still be reduced to "dutiful" daughter by this diminutive 90 year old woman. You gotta love that!
