I'm not really experienced in this enough to say, but a major factor would be that they have decided on me. The couple of times it's happened though, it just seemed to happen, it wasn't an actual logical decision making process.
Business partners or romantic partners?
Huh I swore I picked the love and relationships category but must have picked life by accident. So yes romantic partners.
Sometimes you pick one topic and it changes it to something else. That's why I rarely look at the topic.
Well yes that does happen butwhat traits of hers where you attracted to?
Is she a pixie with an abnormally fat brain?
It's the fatness index. Bub has an extremely fat brain, but he is otherwise completely a pixie with body mass of four point seven nanograms, so...
I don't think only one person chooses to be a partner. It's more of a mutual decision based on feelings, trust, common interests, common principles by which you live, attraction, intellect - so many different components.
It just happens. 乂º◡º乂
I don't really decide. It just happens in the most awkward and amusing way.
