BOZEMAN, MTPrudential Insurance administrative assistant Becky DuBois, 24, was forced to explain herself Tuesday morning after an off-hand insult was not understood by coworker Kimberly Spellman. 'Oh, I just meant, 'This is what a bill looks like,' as in... Well, you said that your parents still pay your credit-card bill for you,' DuBois told Spellman. 'So, I just sorta meant... you know, that you don't know what bills look like.' DuBois then said she didn't mean it as an insult, because she knows that Spellman said she hates it that her parents do that, and that she's totally sorry if Spellman took it that way.
