Agreed - and I think this is a narcissistic assumption: that being nice to other people should automatically result in them being nice to you, as a teacher, parent or partner. The motivation here is for this person to get the adoration of others, to be their 'sun'. It's a pathology. As you note, this is not what teachers do. They are hired to teach - not make friends with kids. It's not what good parents do - because they're supposed to be parenting - not winning a popularity contest. And it's not what a good adult partner does - who wouldn't say 'no' everytime he/she is asked how they feel - because the partner is supposed to be an adult. I often see narcissistic comments like this from people who want to be in relationships where they can get instant adoration. The relationship with students, children and partner in this case is unhealthy. Christopher Lasch wrote about this trend in the US, in: The Culture of Narcissism.
