Your mother was never very present, her work make her stay away from home for days, and when she is, she isn't one of the best people to live with, she believes that you disturb her life and always take out her frustrations on you.

As time went by, you started seeing your neighbor Amelie as a mother figure, she supports you in everything and comforts you when you are sad, just like a mother. 

Now you're ringing her doorbell because you need someone to talk to.
