I believe Mary would "work" more, if it would include meeting rich people, being able to wear Prada dresses and jewellery etc.
The so called bread and butter engagements are just not hers. A pity there're more of them.
She is not very sociable. So far I haven't seen her with many rich friends of her own other than Freddle's rich friends and their spouses. I'm sure she had wanted to break into certain circles in OZ or US earlier years when she made frequent trips, but without a success. It's not a bad thing though, at least she didn't run into jeffrey epstein as MM. Her real passion is designer gears and cameras
