Using the Placidus house system I have Scorpio-Taurus intercepted across the 3rd-9th houses. I have Mercury, Venus and Sun in Taurus; Gemini on MC.
If what you say is true, how come I worked for four different firms which dealt with 'foreign' ships, English as 'foreign' language, 'foreign' currency exchange, and 'foreign' luxury goods. I met and married a 'foreigner', left my native country (Sag I.C.; Jupiter in 12?) to settle abroad (Taurus?) where I have lived the majority of my life (Sun) literally on 'foreign' soil (Earth in 9th)?
If Equal Houses are used, Taurus would be on the 9th house cusp and
Mercury-Venus would be in the 8th. It would need a complete change of 'mind-set' to make their functions 'work' there. It took so much courage to uproot and start a new life elsewhere; this seems to fit Aries on 9th house cusp so adequately.
With Equal house, Scorpio is on my 3rd house cusp. This does not fit either. My siblings and I have always had a friendly, loving and sociable relationship with one another. This is more Libran of nature, and with Venus in 9th, they are as much abroad to me as I am to them.
