Commentary for Berakhot 34:9
אמר רבי יוחנן מוחלפת השיטה רב שישא בריה דרב אידי אמר לעולם לא תחליף דרבנן אדרבנן לא קשיא ק"ש כיון דכ"ע קא קרו ואיהו נמי קרי לא מיחזי כיוהרא הכא כיון דכולי עלמא עבדי מלאכה ואיהו לא קא עביד מיחזי כיוהרא
R. Johanan said : The statement must be reversed; but Rab Shesha b. Rab Iddi said : Thou hast surely no need to reverse the statement, because the Rabbis do not here contradict themselves. In the case of the reading of the Shema' which everybody reads, if [the bridegroom] also reads it, it would not seem presumptuous ; but in the latter instance, since everybody works [on the ninth of Ab] and he does not, it would appear presumptuous.
Abraham Cohen Footnotes to the English Translation of Masechet Berakhot
To remove the contradiction, B. Johanan suggests that in the quoted Mishnah, it is the Rabbis, not Rabban Simeon, who say "Everyone should regard himself as a disciple of the wise."
