Long ago Baba ben Butti would visit the Holy Temple in Jerusalem every day. He'd bring with him sacrifice to be offered on the altar.
Baba knew that his life was filled with doubts and so many opportunities to unintentionally offend his fellow. In his heart he wanted nothing more than to cause no hurt so he brought this atonement "just in case." Perhaps, he thought, I accidentally ignored someone and they were deeply offended. Maybe my prayers were done imperfectly, without real intention.
The kohanim, priests, to whom he brought the animals, told Baba ben Butti that his sacrifice was not welcome the day after Yom Kippur as Baba emerged from the Day of Atonement cleansed of sin.
Consider the life that acknowledges the pain we can bring unwittingly. How much kinder would the world be!
