Who is Lily Aldrin in How I Met Your Mother?

The kindergarten teacher who runs the group · The Apartment

Lily Aldrin (The kindergarten teacher who runs the group) is a character in How I Met Your Mother, part of The Apartment. Lily Aldrin teaches kindergarten, paints, and governs the group's emotional affairs with the quiet absolutism of a Bond villain in cardigans — breaking up Ted's wrong relationships before he notices they're wrong, brokering the gang's treaties from her perch at MacLaren's. Engaged to Marshall since the pilot, she is one half of the show's load-bearing couple, and the keeper of its biggest hidden ledger: her own deferred dreams — art, San Francisco, a credit card situation — which surface at the least convenient moments.
