I've definitely found that there's something to general character traits represented by the different signs - though I'm certain that
it has absolutely NOTHING to do with the relative positions of stars and planets.
First of all - let me clarify:-
I have a technical/scientific background - MPhys-hons (Masters) - "Physics with Optical sciences"
And a lifelong interest in astronomy (NOT
'ology') - I give presentations on the subject.
All this
"You will meet a tall dark stranger" stuff is a steaming pile of horsesh!t
However.... and bear with me a littlle....
It's possible that the time of year you are born could be the reason - As a babe-in-arms you're nothing but a sponge, soaking up everything around you - and people do act differently at different times of the year...
More optimistic as Christmas approaches - Pessimistic soon after - Happier in general during the summer.. etc...
Then there's the weather - generally colder/hotter/wetter at different periods...
More indoor social gatherings during fall/winter, longer nights - More time outdoors in summer, lighter nights....
And it will all add up...
For example, a Sagittarius, your first few months will include Christmas and the early spring, and all the things that go with it.
A Leo, your first few months will be summer, leading into the colder wetter times of the fall....
A LOT more to it than ^^^ That ^^^ but you get the idea.
I could believe that some general personality traits will be formed accordingly....
I'm a Scorpio for the record.
In practice - I really don't get along with Sagittarius or Gemini at all. (I will almost always left-swipe if this info is available)
I do really well socially with Cancer, Capricorn, Taurus, Virgo.
In the bedroom - Scorpios have a bit of a reputation, and I've found that to be generally true when I've been with a Scorp woman (Two Scorps together....

)
I married a Leo - and like most Leos I've known... went great at first, then went to sh!t later. (I won't expand on why... don't want to upset any Leos reading this - but for me, things tend to start well with a Leo, but sooner or later will go South)
