In 1984, I met my wife.
We moved to California that summer. We left Ohio the morning school started, and when we got to California we had two more weeks of summer vacation. I remember thinking, "To make sure I never lose these extra weeks, we must never move back."
My first Sunday in California, August 26th, we went to church and I sat behind my wife in Primary (children's Sunday School). I came home and reported that I knew who I was going to marry.
I realize this is atypical, but it is my experience, so I sometimes find myself thinking, "My kids (aged 11, nine, five, and one) are slackers because they don't even have a spouse picked out yet!" I try to calm down and give them a couple more months before staging an intervention.
