Fans of C.S. Lewis and J.R.R. Tolkien should check out their guest appearance in Jonathan Morris’s comic strip story in the latest Doctor Who Magazine (dated 12 January, cover featuring Matt Smith in a Santa hat with Michael Gambon and Katherine Jenkins). Very pleasing.
edited to add: Today is Tolkien’s birthday! (3 January 1892)
To me, “insist” implies compulsion. I can insist that a member of my staff does something, because I can sack them if they don’t comply. But I can’t insist that a colleague does something, because I have no sanction if they refuse.
