Berachos 8a:
ואמר רבי חייא בר אמי משמיה דעולא לעולם ידור אדם במקום רבו שכל זמן ששמעי בן גרא קיים לא נשא שלמה את בת פרעה והתניא אל ידור לא קשיא הא דכייף ליה הא דלא כייף ליה.
Soncino translation:
R. Hiyya b. Ammi further said in the name of ‘Ulla: A man should always live in the same town as his teacher. For as long as Shimei the son of Gera was alive Solomon did not marry the daughter of Pharaoh. — But it has been taught that he should not live [in the same place]? — There is no contradiction. The former [speaks of a disciple] who is submissive to him, the other [of a disciple] who is not submissive.
Of course, that doesn’t preclude saving things for later…
