What do you mean by that?
In the case of a meal offering, the parts that the priests are allowed to eat do not become permitted until two steps have taken place: the kometz—a handful of flour taken for the altar—and the levona, the frankincense, are both placed on the altar.
The Mishnah on today’s daf asks what happens if someone has an improper intention about eating the meal offering—for example, piggul: planning to eat it at a time when it would be forbidden—but that thought occurs during only one of these steps. According to the Sages, the offering is disqualified as piggul, and anyone who eats it would be liable for karet (a Heavenly punishment), only if the improper thought occurred during both the offering of the kometz/flour and the levona/frankincense. Rabbi Meir disagrees, arguing that even an improper thought during just one of those moments is enough to invalidate the offering. Rav says:
But if he placed the handful with the intent to partake of the remainder the next day and then placed the frankincense in silence, all agree that the meal offering is piggul, as anyone who performs the rites in such a manner performs them in accordance with his initial intent.
And here’s our gem. If you give an initial intention to your actions, everyone will assume that that is your intention from there on out unless you actively make it clear your intentions have changed.
Two lessons: 1) If we don’t actively correct a first impression, others will assume it still defines us. 2) An initial intention sets the tone—silence afterward is often read as consent.
