How I met your mother AU:
Tracy tells the story of how she met Ted.
“Kids, I’ll tell you the story of how I met your father, although there is more than just one story. Over the years we have met multiple times, but when I mean the day we met, I’ll always mean the story of your father teaching the wrong class and how this coincidence led to us eventually meeting for real. So even the decisions you think are irrelevant, can lead you to being at the right place at the right time.”
