You were treated as an adult before you were one
Your taste is Capricorn-restrained and it shows in how you arrive: composed, unhurried, giving very little away. People have assumed competence and seniority in you since you were far too young for either, and you have spent a long time living up to an impression you never set out to create.
The restraint is genuine rather than strategic. You dislike overstatement, you would rather say nothing than something unconsidered, and the effect on a room is that everybody becomes slightly more careful, which is occasionally useful and occasionally lonely.
Read as cool, which is not what is happening
Your reserve is consistently interpreted as detachment or disapproval, and it is neither. You are simply not going to be effusive on first meeting, or on the tenth. Say one warm thing out loud early in any relationship that matters, since your natural manner supplies no evidence and people are drawing conclusions from an absence.
The dry line nobody expected
Under the formality there is a very dry humour that arrives without warning and is funnier for the contrast. It is one of the most likeable things about you and it appears only once you are comfortable. Let it out earlier than you usually do, since it does more to correct the initial impression than any amount of deliberate friendliness.
Well presented, on purpose, always
Your clothes are good, understated and chosen to last, and you would not leave the house in something that undermined how you wanted to be read. That is not vanity; it is an accurate understanding of how much presentation does. Keep it, and let one thing be enjoyable rather than correct, since the whole effect currently has no warmth in it.
Warmth on a long timescale
It takes you years to become close to somebody and the closeness then lasts for decades. People who need affection demonstrated early tend to give up before the good part arrives. Tell them the timescale, plainly, since it is the one piece of information that would keep the right people waiting.
You are auditioning them and they cannot tell
Before you commit you are assessing steadily: their reliability, their prospects, how they behave when something is difficult. The assessment is thorough and completely silent, and the other person experiences it as coolness. Say that you are interested and slow, since that one sentence keeps the person who would pass the assessment from leaving before it concludes.
You would rather be respected than liked
Given a choice you take the version where people take you seriously, and you have quietly traded away a good deal of easy warmth to get it. That trade has served you professionally. Reverse it in two friendships deliberately, since respect is a poor substitute for company on a bad evening and you have plenty of the first.
You carry it in the back and the jaw
Responsibility is held physically here: the shoulders, the lower back, the jaw at the end of a long week. You are unlikely to describe yourself as under strain and your body will describe it for you. Treat regular physical maintenance as part of the job rather than as an indulgence, since nothing else about your habits is going to change.
You have been serious since the beginning
A good deal of ordinary lightness was skipped, either because it was not available or because you decided early that it was not for you. That is worth revisiting rather than accepting. Take up something entirely frivolous and be bad at it, since the capacity for unearned enjoyment is the one thing your temperament will not supply on its own.
Given responsibility before the title
People hand you things because you look as though you will handle them, and you always do, frequently without the authority or the pay that should accompany them. That pattern will continue indefinitely unless you interrupt it. Ask for the title at the point you take the work, since afterwards it reads as a complaint rather than as a condition.
