After you ask a question on a legal position or strategy, listen to the explanation and take notes. Even better, record the conversation. Unless the lawyer is being paid by the hour, no attorney wants to waste time explaining the same thing numerous times.
Before you hang up or leave a meeting, ask questions. If you don't understand it, ask the attorney to put it in layman's terms. After you get home, if you have additional questions, ask.
However, there is no excuse to have to ask the same question 5 times over numerous weeks because you don't listen and take notes.
