I was thunderstruck the first time someone said to me, "Of course, the
basic family unit is mother and child."  How culture-bound we can be.  That
the irreducible, fundamental family unit for any mammal is mother-child,
not mother-father-child, had just never occurred me.  Duh!

(But then, I was in third grade before I learned that not everyone has a
Christmas tree.  Thunderstruck again!  This time by Ruthy Siegel in the
girls' bathroom at school.)
