I'm going to mention it because I think that it is an important point, as it is often confused on this forum. The point is the difference between a caregiver and a "caregiver"; that is, a socionics caregiver versus more common notions of the term. I'll start with an example. I've heard of people on this forum saying that someone crying out for warmth is "looking for a caregiver." In socionics, being a caregiver has nothing to do with warmth and reciprocity. Caregivers are Si-egos. Therefore, the type of care they give is generally physical; e.g., fixing nice food, helping maintain health, or making radiant gifts during the festive season. It is not supposed to have anything to do with showing warmth, sincerity, or closeness, like the stereotypical kind-hearted nurse who tries to bring emotional warmth through their ego-functions. The kind of "nursing" that is involved can be emotionally-spirited, but it is generally aimed at the senses. If you're still not convinced, consider that some Te-egos are caregivers, and yet they are not supposed to be especially warm. I should also mention that I think this is one of the main confusions between "true" Alpha SFs and those whose type is debatable, as ESFjs and ISFps are not supposed to be emotionally sweet and caring as much as physically sweet and caring.
