But then Tom was known to work in this field and doing Tv occasionally long before his mother actually became the future queen. So he simply continued as he did before and it has been known that he does not talk about his mother apart from her participating in a way with one of the books, like donating a recipe. Pippa became famous through her connection and used this to get a chance to write her book (considering her choice of profession, she would have done so anyway someday, but how and for which advance on the royalities has to do with her brother-in-law's identity). So I believe it is in very good taste not to do interviews now and wait with that till she has to tell things about her own merits instead of about her sister. I'm sure she will come into a position when people are interested in her opinions and experiences but thus far it's not yet happening.
