Neighbors

So, it turns out that the family who lives behind us has 3 kids around my kids age.  It also turns out that the parents are lawyers and that I used to work in the same firm as the dad.  Last night, they came for pizza and margaritas and the kids played.  We were out of limes and so we sent 2 kids back to their house to get limes and ice.  It feels like the 50's in a great way.  How long b/f someone comes to borrow a cup of sugar?  I love the possibilities :)
