We celebrated #18 both with and without the kids. A TIME magazine article came out the same week as our anniversary with a cover story on marriage (and how it is under siege). It reminded me how grateful I am for our marriage, and I decided I want the kids to see it as a family holiday at least as important as a birthday. So we got red and white balloons, a "sweetheart cake" from Baskin Robbins, lit 18 candles and sang "happy anniversary" to ourselves with the kids. Then we got a babysitter and enjoyed dinner out and a long walk in a beautiful park at sunset.
I forgot to take pictures but I will try to remember that next year.
