Aunt Lisa's next door neighbors have a little girl Jessica's age, so when we visit, Jessica likes to go play with Caroline. Well, when we were there this past week, she came in one evening and asked if it was okay to go with Caroline to her "brother's girlfriend's" house. Well, of course, the first thing that flashed through my mind was that I didn't know his girlfriend and I wasn't sure that I wanted her to go, and that I didn't know where she lived.
A quick consult with Aunt Lisa reminded me that Caroline's brother is Xander's age, and that the 3 year old girlfriend in question lived just down the street.
I let her go.
