do you know bob grady? >> guest: i know bob grady; i was in the very office that was described. c-span: why do people do that? >> guest: why do people hang pictures like that in their offices? there is a kind of white house etiquette and white house style of personal self-congratulation. it's very odd; i don't know that it attains anywhere else in the recorded world quite, but it is a matter of style that people hang photos of themselves with celebrities, political celebrities. c-span: did you? >> guest: i did not, no. i had only one such picture, but i still don't have it hanging in my office -- with ronald reagan. but i, in fact, don't have it hanging in my office. i don't wish to make any great claims for my character; it's just not my kind of style. but there is a generic white house style that has been the case through administrations, i'm sure, since the invention of the photograph and i'm sure is going on in the clinton white house now. c-span: when people walk in that room now, do they talk about people like bob grady, who had all the photos on the wall? >> guest: grady
