history: I'm so upset that people don't understand what I'm saying.  I was trying to explain to a friend why something is happening and they just couldn't get it. I don't get why they couldn't understand me.  ohh_comma_ what did you try to explain them?
current: I was trying to explain to them why the Great Recession was caused by the recycling of petrodollars and an unrestrained financial market.
