My old self and my current self hold quite different views. I find his enthusiasms embarrassing and even a little insincere. I want to tell him to grow up.
(Which, of course, he did.)
There he is in the corner now. My God, he's got long hair and a beard!
And where's his sense of humour?
What a sweetly sanctimonious face! How his eyes glisten with compassion! Does he presume to pity me?
Well let him; I don't give a stuff what he thinks!
