If you don't listen to the advice here to not meet with the elders, or you feel
cornered by them because of living in your parents' home, then the best alternative
is to say virtually nothing.
"I agreed to meet with you at my parents request. I am here to listen."
Well, we wanted to ask you ..... and ....."
"Okay, I said I was here to listen, not to provide any information to you about my life."
"Well there are accusations of ...."
"That's all they are is accusations."
"So are you denying them?"
"I am not here to confirm or deny anything. I am here to listen to your counsel."
"We can't really help you if you don't tell us anything."
"Then this will probably be a short meeting."
