3, in real life. These are people I went to school k-12 with, 2 females and 1 male (I am female). All 4 of us happily married and our spouses like each other. We are now in 4 states, from FL to NY, one on the west coast and me, in the DMV. All 3 were at my wedding and I was at all three of theirs. For the 3 out of 4 couples that have kids, all are in college so we can, and do, travel easily to see each other for occaisional long weekends. My girl friends and I were all SAHMs, spouses and the guy friend all do different things (Computers/IT, laywer/politics, Telecom, and commercial real estate).
Contrast that with college, I am in touch with 1 in real life (no kids, consultant and economist)
