So...I'm looking through DeDe's depo for clues:

I noticed that she first gets sensitive about the questions and takes the fifth when she's asked whether Ms. Hockensmith paid her for the gardening work she did at Ms. Hockensmith's house to get ready for Ms. Hockensmith's event (p. 12-13). So that seems to be something that she sees as "dangerous territory" for her. It isn't the work itself that's sensitive, because she talks about that for quite a while after. What could be sensitive about whether she got paid for the work? She had already said she was paid for hostessing the event but not for gardening, so this was really just a throwaway follow-up question that shouldn't have set up any red flags. Also, before she took the fifth, she answered "I don't remember" and then changed her answer to take the 5th. So we can assume that she does, indeed, remember whether she got paid but DOES NOT want to say. Why not??
ETA: Oh, I see on p. 44 she says it would have been a violation to receive her unemployment benefits and not report income received.
