When reading this article, one of the things that spring to my mind is the saying: "opposites attract". I've frequently found myself taking this for fact even though I know that 2 individuals that are completely different usually don't date.
The reason for the saying, I suppose, is because 2 people very alike would bore each other. They would never stimulate the other. They would never bring something new and exciting to the relationship.
How does this relate to this article? For once, the couple here sounds very much alike and, according to my very unscientific statement, would have a somewhat stalemate relationship. Yet, reading this gives me anything but this feeling.
What's the whole point of my post? Well, I'm a bit torn in the 2 views on relationship I just presented. Should I look for someone who is very different from me or should I look for someone I can laugh with and whose company I enjoy? My guess is that it's a mix between those 2, but is it a 50/50 spread? Perhaps 10/90? I don't know. Am I just theory crafting too much? Probably.
