DeeDee, assuming you haven't made a mistake on something (which is fixable by your attorney), it sounds like you have a hardcase for a trustee.
Some trustees get a real power trip. Here's some tips
1) Make your attorney work for that retainer. The key here is your attorney will (hopefully) only have this one case with you, but he might be working with this trustee on other cases for the next 20 years. Sometimes YOUR attorney does not object as much as he could....(no rockee boatee)
2)Trustees have ONE job: to ensure that the ESTATE is properly handled. That means inventory, examination and liquidation if aproporiate. While the trustee can (in layman's terms) protest your discharge with proof, the TRUSTEE CANNOT abuse you, call you names, or treat you like a pile of poop. If the trustee is doing these things, your attorney should be right there objecting.
Trustees can ask polite questions and YOU can ask them to clarify their questions.
Bad Question, Bad Trustee:
Trustee "Explain yourself and these expenses!"
You: "Can you be more specific? Precisely which expense are you asking about?"
Trustee

nasty) "All of them!"
You: "Okay, let's start at the top."
Just be cool and calm and explain.
If things get REALLY bad and he/she/it says something like this:
Trustee: "Are you too stupid to remember what you lied about?"
You: "Please conduct yourself with the decorum with US Trustee requires and treat me with the respect I deserve. I'm not a criminal on trial." and then tell your lawyer to find his voice.
Most trustees are actually quite normal.
Good Question:
Trustee: "Mrs. X, I've got a question about your living expenses; Medical seems high, and what goes into Misc.?"
YOU: Calmly explain what medical is, and what misc. is.
Don't forget that trustees also get weasel petitioneers that list things like "Misc $1000 per month", and then can't explain what misc. is.
I personally believe most people get in trouble with their trustees simply because of expenses look so kooky many times. People constantly estimate rather than simply looking back over their records and seeing how they spent their money.
I had one client list $1000 for the house payment when it was only $705. I really don't believe they were trying to mislead. If you asked them what the house payment was, they said "$1000 a month" but the reality was alittle different. Guess they were just to lazy to verify the numbers.
