I haven’t ever heard that combination before. Good suggestion, sir!
I have taken to just taking to saying a Hail Mary for any person who might cross my path with whom I have might be having a difficult time, or while driving and being stopped by a train, I say a decade of the Rosary.
Another thing, whenever I hear a siren, I completely stop what I am doing, even if it is a conversation, and say a silent Hail Mary for the people the siren is going to.
I pray the Rosary on the train every morning; the trip, if it is on time or near it, takes exactly the right time. I pray the Fatima Prayer for those in my car who are most need of His mercy, especially the mothers of young, vigorus men who remain glued to their seats pretending to be asleep while the elderly and the women stand.... On days when I do not take the train I pray with Mother Angelica.
