The year is 2030. Ted Mosby is relaying the story of how he met his wife to
his daughter and son. The story starts in the year 2005, when then
twenty-seven year old architect Ted was spurred on to want to get married
after lawyer Marshall Eriksen and kindergarten teacher Lily Aldrin, his
best friends from their college days at Wesleyan and Marshall who was his
roommate at the time, got engaged after nine years of dating each other.
Ted's new quest in life was much to the dismay of his womanizing friend,
Barney Stinson. But soon after Marshall and Lily's engagement, Ted believed
that his life mate was going to be news reporter and aspiring news anchor
Robin Scherbatsky, who, despite having had a romantic relationship with her
after this time, ended up being who the kids know as their "Aunt" Robin. As
Ted relays the story to his kids, the constants are that their Uncle
Marshall, Aunt Lily, Uncle Barney and Aunt Robin are always in the picture
and thus have something to do with how he got together with their mother.
