There's a scene in the 2012 indie classic Frances Ha where Frances describes her perfect relationship as being separated from someone at a party, but making eye contact across the crowded room and knowing that you both just get each other. This is precisely the relationship between me and my best friend/Taurus queen, Hanna. As a self-reliant Capricorn, expressing my skepticism to a Taurus, another one of the zodiac signs who are suspicious in new relationships, is healing, helpful, and often darkly hysterical. No matter how many dates I've been on with a new cutie or how excited I am about a new relationship, it takes me a while to really investigate what a new boo is all about (which, as Hanna reminds me, is probably because I use words like "investigate" when talking about dating).
Of course, Capricorns and Taureans are in good company with our dating-related suspicion: Cancer and Scorpio are known for being skeptical of new love as well. They're also the opposing signs for Capricorn and Taurus, providing harmony and balance between the head and the heart.
Although everyone may get a little skeptical sometimes, these four signs tend to proceed with a little *extra* caution.
