St. Ambrose

St. Ambrose seemed to have a great impact on St. Augustine as well as on his mother. When St. Ambrose preached he answered many of the questions that Augustine had been asking himself. But, in fact, when Ambrose was not preaching, he became so deeply emerged in reading that Augustine did not wish to interrupt him. Ambrose was intensley focused. So a few of Augstine's questions went unanswered until a later sermon from St. Ambrose.

Therefore, St. Ambrose didn't have as much of an impact as he could have had if Augustine had not been afraid of disturbing his reading.
