what dd aunt polly apologize to tom?

During supper, however, Tom's moods are lowered when Aunt Polly raps his knuckles for attempting to steal sugar. When Sid reaches for the sugar-bowl behind Polly's back, he drops the bowl onto the floor. When Aunt Polly returns, she immediately begins to beat Tom. When she learns that it was Sid who was at fault, she doesn't apologize but instead justifies her beating, though inside she longs to say something loving to Tom.
