If people were words, you could kinda make some lame analogies, so that’s what I’m going to do.
You could think of it like this: some people are super interested in the same stuff you are, but the personalities are completely different and kind of clash. That’s like those words that are basically antonyms but they share many of the same letters. For example: Incredible vs Incredulous. Not full antonyms, but they definitely seem contrasting, yet they share some of the exact same letters.
I think of those ideal relationships and marriages being those synonyms that sound nothing alike but have almost the exact same meaning. Made up of completely different letters (opposites attract, right?) But even in all the differences, they’re going after the same thing, they have the same end goal. You have a similar meaning behind your life.
The letters might be the different interests that they have. They might be different backgrounds, different skin colors, etc. The sky’s the limit with this lame analogies. What parallel can you pull from this analogy?
