My favorite series

I don't remember the first day I saw How I met your mother. It was like 6 years ago. This series always like me since the first chapter. 
How I Met Your Mother is about how the name of the series say, is the history of how the main character, Ted Mosby met her wife and tells the story to his sons. In this story are very importants his friends:
Marshall Eriksen, Lily Aldrin. Robin Scherbatsky, Barney Stinson.
What I like about this How I Met Your Mother are the charecters. Every characters have their personality and their story (the story of each character is gradually revealed during the every season) and all together are magnificent.
