this man

 Bunyan neglected to mention this man,
describing Vanity Fair.

Unless, of course, he did it discreetly
in Mr. Facing-both-ways.

CHRISTIAN:
Pray, who are your kindred,
if a man may be so bold?

BY-ENDS:
My Lord Turn-about,
my Lord Time-server,

my Lord Fair-speech,
Mr. Smooth-man,
Mr. Facing-both-ways,

Mr. Any-thing, and
Mr. Two-tongues...

 My great-grandfather was a waterman,
looking one way and rowing another...
