A man stopped HaRav Caim Ozer Grodzinsky Zatzal, the Rav of Vilna and the Gadol and Posek Hador in the pre-WWII era, to ask for directions how to get to his destination.
This man was stuttering, so Rav Chaim Ozer not only gave him directions but also walked him all the way to his destination.
The students asked why? R Chaim Ozer answered "If I didn't take him there he might have needed to ask direction again and then he might get embarrassed."
SMALL DEED. BIG PERSON.
