You cannot look away. You also cannot turn them into you.
The two of you
Scorpio. You feel real when it is honest, even if it is heavy. People see the intensity. They trust you with the thing they will not say elsewhere.
Taurus. You feel real when something stays. People see the calm, and the person who can be leaned on.
What wears it out
Small talk that asks you to be fine drains you. So does a secret kept from you.
Being rushed drains you. A plan changed under you feels like disrespect, not flexibility.
Scorpio feels it first and explains later and does not like to be moved once settled. Taurus wants something solid and does not like to be moved once settled.
Each of you is what the other is not. It holds when the difference stays interesting. It breaks when one of you starts correcting the other. Together, it shows up as the person across the table. The other way around, it shows up as the person across the table.
This is the answer people want before anyone knows a birth time. Two real people have more than a sun sign. If it matters, cast both charts.
