I remember how patiently my father taught me how to tie my shoes. Someone had complained that my shoes were always untied, but this was just after I had started school, and while I had noticed that my shoelaces were tripping me, I did not know what to do about it. I asked my mother but she turned away in her usual sulk that threatened violence, so I asked my father, who readily showed me.
To illustrate this random thought from more than sixty years ago, here are random fishes.
