When a man starts
explaining a concept you already told him you understand,
instead of saying “I know” over and over until you die, try one of these:

• Ok, which aspect is confusing you?
• It seems like
  you have the basics down; Would you like me to recommend some good articles so you can get a more nuanced understanding?
• So did
  you have a specific question, or do you just want a more in depth
  explanation?
