Are you all familiar with Spiritual Gifts assesment?
D4ML is the "worker bee", "Beaver" or "Melencholic" of the R. They tend not to be terribly emotional people. Very hard workers, very organized, introverted but can force themselves to get out, but it does drain them. Prone to depression. Beat themselves up TERRIBLY when mistakes are made, because they are so very careful when they make any major decisions.
They are engineers, accountants, scientists, computer programers. I have a friend that is a nurse that is melencholic so you do find them in other fields. They are the "treasurers" and "secretaries" of clubs.
Her H I think is a "Golden Retriever" or "Phlegmatic", but this I'm not sure of still. This personality is very prone to being co-dependent. Extreme people pleasers. Very easy going and laid back. They HATE conflict (like between D4ML and parents--this would kill a Plegmatic type). Not terribly ambitious usually--they are too easy going and don't like to "fight their way to the top" because of wanting to please everyone. They DO get to the "top" sometimes because everyone likes them and they are good at what they do, but it's not usually real comfortable for them. They are usually artsy.
Around here D4ML, the next "relationship" is hopefully your H
