What does it mean to be taken for granted?
When you take someone for granted, it basically means that you know that you have them and feel like they will always be with you and belong to you. You accept it like it's the only way for them, to stay with you - no real sense of appreciation.
To get something you want and don't appriaciate it!!:)
You're lucky if you don't know.
Like people take advantage of you becuase your nice and always help them out in a time of need and dont appreciate what you do.
