I have two friends who are truth tellers.
Number 1 - Sun, Moon, and Mercury in Sagittarius. Moon conjunct Mercury in the 1st house. Sun opposite Jupiter in Gemini. Jupiter square Uranus, the “truth shall set you free” aspect. Also, Uranus squares her Sun, making it a t-square.
Number 2 - Sun and Mercury in Aquarius. Mercury rules her Virgo rising chart. Jupiter conjunct Uranus, also the “truth shall set you free.”

They both also have Saturn connected to the 3rd house. They take communication seriously. In neither case, does the Saturn-3rd house connection inhibit their communications. Rather, they sometimes pay a price for their truth telling.

The Sadge truth teller is simply a direct, candid person who sometimes puts her foot in her mouth and later regrets it. The Aquarian truth teller is more inclined to speak the truth as a mission to bust the keepers of dirty secrets.

2 people come to mind, they both can’t help but blurt out the truth. One is an Aires, with Merc and Mars also in Aires. But people love and respect her for her candidness.

The other one is Aquarious, and her truth can come out as hurtful or unessesary, but is totally oblivious to other people’s feelings

Man, my comment didn’t go through. Blah!

Me. Its a running joke around here that I am Janice (and Ohhh if these people I live with knew exactly how MUCH Janice I keep locked in my mind and away from my mouth!) I think just like her. Sometimes when Storm & I are watching some train wreck of a reality show together, he will say “Do Janice!” . Its great for entertainment, but I dont think he truly gets that I think that way ALL of the time. Not sure about the astrology behind it, I just know that you CANT be a Janice full time, people dont take it well.

Oh, I just wanted to add that I generally really appreciate Sagittarian bluntness. A cousin of mine has a stellium in the sign and we’ve always gotten along like wine and cigarettes.

I am an obvious blurting (seemingly involuntary) truth teller, [but Never on a small one-on-one scale as in, wow you have gained weight!]. I do it on a much larger scale. Here is the #1 example. when I was a college professor, and from the front of the classroom, I told the students the truth about something that the administration was doing to the program. It had every bearing on the students. They had every right to know. I felt it was an ethical issue. I had been told to lie, and all of my colleagues lied to the students. I not only wouldn’t lie, I wouldn’t be silenced either. For this I was fired from my tenure-track over night and banned from the campus. (that was 7 years ago and I have never once regretted what I did).

Here is the astrological information that (I think?) is relevant. Late Sag on the MC with Rahu within 2 degrees and late Pisces on the AC (all a bunch of Jupiter!). Then, Jupiter is in the 5th house in Cancer conjunct Uranus in Cancer within ~1 degree (Jup and Uranus very tight). Uranus rules the 12th house.

I don’t know if this is some kind of truth-telling confuguration? Moon is also in the 5th, but in Leo; Leo rules the 6th, which holds Pluto in Leo, and Pluto rules the 8th which holds Saturn in Scorpio.
