Her thesis is silly then, restricting the movements and ways of the Holy Spirit. 

Very pharasaical.  Rigorist even. 

The Holy Spirit is working all the time, often in very quiet ways.

The spur we get to apologize to someone comes from the Holy Spirit, no one else needs to be around.

The movement we get to return to a state of grace by going to Confession is a private action.

The movement we receive to drive more calmly and attentively...

It sounds like Mary's trying to "put God in a box" and limit His actions.  "here's the only way the Holy Spirit acts, I've decided". 

It's really a preposterous thesis.
