Write a short poem on 'school' or 'school' children'.​

My child and I hold hands on the way to school,And when I leave him at the first-grade doorHe cries a little but is brave; he doesLet go. My selfish tears remind me howI cried before that door a life ago.I may have had a hard time letting go.Each fall the children must endure togetherWhat every child also endures alone:Learning the alphabet, the integers,Three dozen bits and pieces of a stuffSo arbitrary, so peremptory,That worlds invisible and visible
