5. Women with this name are extremely rare. They are honest, loyal, creative, sensitive, compassionate, forgiving, serious but humorous. Theta's most often take life seriously, are a good judge of character but befriends anyone they meet. Theta's are very deep thinkers and feelers, meaning they contemplate every aspect of life and when they love, they love deep and long. Theta's are sensitive and look for the good in others. Theta's rarely accept defeat and dig in deeper if you tell them something can't be done. The last place on earth you ever want to be is to be the one that pushed a Theta in to giving up, as this is rare and to be accomplished you have to be very cold at heart.
