These are largely based on people I know :)
Capricorn risings always appear disinterested or annoyed at first. If they have prominent water placements, though, this fades fast and they show their sweet side. (Ex. the cap rising i knew had both their sun and moon in cancer !!)
Gemini risings are big talkers, though the conversation stays surface level until they trust you.
Capricorn moons aren't as cold as people think. they are emotional, they just have to trust you first.
i always feel safest around people with heavy earth and water influence. for example, one of my closest friends is a Taurus sun, Capricorn moon, and they make me feel the most safe out of everyone i know.
Leo placements are the most outgoing. the ones i know are ALWAYS out with friends (of course, this depends on other placements, too!!)
Aquarius placements can be very emotionally distant (esp moon and rising)
Aquarius mars people are the calmest people ever. takes a lot to get em angry.
Cancer placements in men make them very quiet people, even when mixed with fire.
Want a Gemini venus to crush on you? let them talk, and be interested in what they say!
Cancer mars people express anger inwardly towards themselves rather than lashing out. they also cry when they're angry.
Pisces people (sun, moon and rising) lie like its their JOB. of course, not everyone with this placement will fit this, but a lot that i know do.
Leo venus women are SO charming!! they know exactly what to say to pull you and they say it WELL.
Aries venus people move on really quickly after a relationship.
