Hi, Victoria. Thanks for your post. As you know, we on this site enjoy when others surf the web and find tidbits of information about Diana, whether or not it's flattering to her. As far as I'm concerned, that's what you did. I think it says a lot that you felt this article would a fair airing on this site--you wouldn't hold it back because the article has a negative tone.
That said, I think the members of this group do what we always do when such an article is found: comment on it, dissect it, and otherwise give our humble opinions. So I think it's reasonable to take any comments about this article in that spirit.
I have no idea if the allegation of crankiness in the article is accurate or not. I know I've read that Diana has a long history of enjoying outdoor activities, such as skiing, mountain-biking and fishing with her Dad. As a writer and sometime-journalist, I also noticed in the article that none of the people alleging crankiness would put their names on the record. I don't mind complaining within reason (I do my fair share) but one has to notice, too, that the people supposedly talking about Diana also are complaining -- this time, though, it would be about Diana.
If she was cranky (don't we all get way sometimes?) the article seems to make a big deal that she turned the crankiness off when something interrupted the mood. It's not clear what that something is. I enjoy reading about psychology, and one of the things I remember reading years ago was that it's not hypocritical if you're mad and then someone else comes into the group or a different event takes place and, basically, interrupts your mood then you turn uncranky. That's a natural response--I think we've all been in that position. What this psychology article said is that it would hypocritical if, after the interrupting event, you suddenly revert back to the crankiness. Then you can be sure that the uncrankiness was just an act. When I read that, I thought it rang true with my experience.
Anyone here remember the old Mary Tyler Moore show from the early 1970s? (I'm dating myself here, but I'll continue.

) I'm thinking about the character of Sue Ann Nivens, the "Happy Homemaker." She would come into the newsroom dripping venom, then someone she was trying to impress would come in and she'd change her tune. Then after that person left, she'd resume her earlier tone.
Just my ten cents' worth of pop psychology.
