One day in 1926 I met him at the gate of the British Museum in his private is uniform. «Hullo, Lawrence.» «Do you recognize me?» «Of course.» Then he said, «The whole afternoon i have been walking about the Museum where every attendant used to know me, and not a single one recognized me, till I inquired about someone I missed. Then the man knew me.» Quise so - what was the good of disguising if no one recognized him?
