Who is your Maude?

There's this fantastic movie from the seventies by the name of Harold and Maude. It's about a young well-to-do boy (Harold) who has a bizarre fascination with death and whose mother keeps trying to marry him to boring, ordinary girls. He meets a wonderfully crazy old woman (Maude) who shows him the beautiful things about living, and they have awesome, hilarious adventures.

So I was wondering, who is my "Maude" in life? There was a couple different people I think it could be, and I had a hard time narrowing it down. But I think I finally figured it out.
