I have to dodge my wife and my daughter, who lives in the basement. My DADT wife know, and I can always ask her to call before she heads home. That gives me about 15 minutes to stuff Steffi in a closet.
My daughter is another story. She doesn't know and I'm supposed to not let here find out. I can never figure out when she will be home. When she's out at night, it's either a date, GNO, babysitting or staff meeting, and even she doesn't know how long she'll be out.
The funny thing is that she doesn't have a curfew, as long as she texts out that she's not coming home, so we won't have to call hospitals and police stations when she's not home by morning. I, in theory at least, have a midnight curfew when I'm out with the girls.
