Complaining parents

Complained and complained
they did,
those parents of my children!

Won't they say a word of praise
for me,
put forth good words to my principal,
make my life a pleasure
and teaching a joy?

Still, I commit them to you,
these complaining parents,
who are not my enemies,
but who make my life sometimes a misery!

Give me your patience, dear Lord,
to deal with parents like these!
