You are demanding this lady love you and invite you to a very personal thing. So what if she invited the nurses and doctors? You expect to receive what you give and maybe what you give is not wanted. So in essence, you are not really giving anything. You are expecting some kind of reward whether it is love or money or affluence or something. you EXPECT something in return instead of freely giving whatever it is you expect to be rewarded for.
It doesn't work that way.
Its more of a disappointment. I am not demanding anything.
I was showing a contrast by using this story. That is all.
