Once a Hasidic rebbe and his student, a distinguished Torah scholar, had differing recollections of a statement in the Tosafot commentary.
Although the scholar had seen that passage just a few days before, the rebbe said, “I have not seen it for fifteen years, yet I am certain that I am right.”
When he was proved correct, the abashed scholar asked him how he could remember so well.
The rebbe asked him, “Do you remember your wedding?”
“Certainly,” he said.
“Do you recall who accompanied you to the canopy, who stood to your right, and who veiled the bride?”
“Of course.” “For me,” the rebbe said, “every time I learn Torah is like a wedding.”
