Pesachim 51 - January 11, 27 Tevet

Study Guide Pesachim 51 Today’s Daf is sponsored by Paula Winning in memory of Rabbi Robert (Ruby) David, z"l father of Suri Davis Stern. "In memory of someone who took pride in his learning and his transmission of his learning to his family and his students, particularly my dear friend Suri Davis Stern." The gemara brings a few cases where people wanted to change the custom in their town and the rabbis reactions. When is this principle used "things that are permitted that people decided to be stringent about and forbid, one cannot permit in front of them"? Is it only referring to Kutim? Can one permit  a custom that is a mistake? Rabba bar Chana came from Israel to Babylonia and ate the fat on the stomach that was a subject of debate between the rabbis in Israel and Babylonia. When the rabbis came, he hid what he was doing. Abaye commented that he treated them as if they were Kutim. Why didn't he keep the stringency of the place where he went? Abaye and Rava each bring a different answer. How do the words of the mishna "one should not do anything different so as not to create conflict" with the case of one who doesn't work going to the place where people do work?
