On Monday mornings in nice weather, Diana would ask, “Where did you go this weekend, Mrs. Robertson?” She knew we made frequent trips outside London. Other English friends would tell us about their favorite spots, but Diana was not forthcoming with travel suggestions. At the time, I assumed that she might not have seen as much of England and Scotland as we did during that year. Diana enjoyed our enthusiasm for her country--its natural beauty, its stately homes and castles, its history. She must have smiled inside when I would tell her of my pleasure in the architecture, paintings, and furniture I saw in England’s famous mansions. She’d grown up in one! And she would always ask, “How did Patrick enjoy…Warwick Castle or Canterbury Cathedral or Dartmoor?” Patrick was a very good-natured sightseer.
In return, I would ask, “And how was your weekend?”, leaving it up to her to say as little or as much as she chose. I would not have asked specifically, “What did you do last weekend?” She would answer politely and briefly, “Fine,” or “Lovely,” maybe mentioning that she’d been out in the country. Of course, I didn’t know “the country” meant a huge estate that had been in the family for centuries. Diana was unfailingly polite but sparing of any details. She considered her personal life just that, personal. She was careful never to give us a clue about her background. If she did not volunteer information, something in her manner told me I should not intrude. She may not have even been aware of this perception I had. I viewed her understated manner as appealing and discreet, not as off-putting or unfriendly.
Clearly, Diana did not want us to know who she was. We may possibly have been the only people Diana ever knew who had no idea who she was. We welcomed her into our home and trusted her with our child for what she was. This may have been one reason she stayed in touch with us over the years.
