A friendly notion is not developed overnight. It is developed by gradual and a bit of slow thinking.
A notion can be to help somebody, to do good friendly work or to be simply nice.
But remember that notion must emanate from your heart.
Otherwise, if you try to act friendly and you have various feelings which consist of hatred, unfriendliness, idiocy, revenge, then you are standing in a boiling soup. Most of us have friendly notion sometime or the other, but whether we act on it or not the world speaks for it.
