RBBM :I completely disagree about the standing appointment Theory. I never have believed that she was going to meet someone that day there is just simply zero evidence to support it. This girl could have whatever she wants in life. By all accounts she had things in order and certainly would not have to meet people secretly. JMO.
Also to quote you, where does it say EXPLICITLY that her runs were "she had a regular routine of taking a walk/run JUST before boarding the bus". Please provide a link to some video or article evidence which states this EXPLICITY. I think this is simply an Oversimplification or generalization of her usual "routine" of exercising while in Princeton. I could be wrong and you could be right. If you can show me some actual evidence, I'd be inclined to join your side.
And that doesn't make sense to begin with because JUST before boarding the bus to NYC we had to have someone drive her 35 minutes to Worcester.
Young women do have affairs sometimes, with people who are "unavailable". And they don't tell their close family members. Just a thought, NOT saying VM was in this situation. But, anything is possible. It was hot that early afternoon, wonder why she chose to run then ?
