You don't have to be qualified in order to be able to read their judgement, which is expressed in plain English. You just need to be able to read. I don't have to be any good at football to know what a great player Philippe Coutinho is, I don't have to be a fiddle virtuoso to know that the Pastoral Symphony is great music and I don't have to be a Wordsworth in order to appreciate the poems of John Donne. In other words, blow it out yo' ass, Keith.
