I wasn't getting on you, people make mistakes. I once came within 30 miles of China's airspace due to a training exercise and we lost sight of the situation, but I knew China was there, just like you should know the president's house is there, or the Space Shuttle is there, or the Super Bowl is there, or Disney World is there, or wherever. My only advice which I am not sure if it was said is Always, Always, Always file a flight plan.
