(excerpt) So much that adults do and say makes little sense in the minds of children. I can’t imagine that I was the only small child of Christian parents who ever puzzled over the oddity of a day that came once a year, just before Easter. It was Monday Thursday, a day that was somehow two days of the week at once. Like the official lyrics of several hymns I’d memorized by hearing them sung repeatedly, the name of this peculiar Thursday got straightened out, at least partially, when I learned to read. Even though “Maundy” made no sense, it made better sense than Monday Thursday.
