1 + 2 = mmh.
I’m poor at maths, but let’s try something:
1. Some of us believe everyone has a soul mate.
2. Most of us get married to or have a relationship with someone who lives and grew up in the same country.
1 + 2 = Our soul mate grew up and lives in the same country as we do.
No soul mates for those who left their home country. Oops.
