We first met in 3rd grade, which would have been 50 years ago. We used to sometimes walk home together from school — we lived about 4 blocks apart — in junior high, about 43, maybe 44 years ago. I worked up the nerve to ask her out on one date in high school, the homecoming dance in 1974, which was 41 years ago. We started dating regularly in 1976, so 39 years ago. We took our time with the courtship, and got married over spring break while we were in grad school, on 16 March 1980, 35 years ago.
It seems kind of silly to say that today is our anniversary. It was more of a long and ongoing process with a few arbitrary dates flagged as discrete points in the evolution of a relationship.
