Sometimes cultures think they're evolving by taking long kept rituals and rites and tossing them out the window. Usually, it is replaced with a ritual that adds more freedom of choice. A ritual that lets the human who is living with the consequences make the decisions.
This is a bad thing.
Example: arranged marriage.
Why did we let this go?
When you pick your own spouse and do mating by trial and error, there is one fatal flaw.
You get exes.
I have an ex from about fifteen years ago who I adore. This is because we don't talk to each other. I have successfully expunged all exes from my life (a few I miss, so if you're an ex, please don't think I don't like you, I just think I still like you because you're not in my life).
If someone is not good to date, they're likely not all that good in the friend department. If someone chooses to stay friends with exes, aren't they actually claiming friendship as a demotion?
Wait, I gotta make sure. Okay, if I broke up with someone because they were selfish and manipulative, then I wouldn't "promote" them to friend. If I broke up with someone because they were selfish and manipulative, then I should demote them.
If I become friends with this person, then I'm demoting them to friend.
Oh....wait. If I broke up with someone because we're "different"...not bad...just different...then, hm....then they could be laterally moved to friend. But if I like someone, and we're having sex, I think that makes them a good candidate for mate-dom.
Different? Why dump a person for being different?
Okay, I'm really not getting why exes should stay friends.
Wait...wait...I got an ex who's cool. We really just didn't work sexually. Hm...But that was ended early. Early is good. Almost makes them not an ex, right? Er.
I got another ex who's okay. But I won't give details so all my other exes will think they're this paragraph.
Okay, so exes who are exes purely from being sexually imcompatible are cool for friendships. That's a lateral move.
Exes who are exes because they aren't one's vision for a lifemate..well, that's lame. This is lame action. Change vision, people! Date the nerd/geek/slightly anti-social person!
Exes who are exes because you find out they told you things you found out were lies and you watch them manipulate a situation so they look innocent when they aren't...well, that is an ex worthy of expungement. Or one who borrows your car and dents it and you find beer cans in the backseat...that one isn't good to keep around. Or the one who comes home from vacation with some woman's underwear...Why be his friend? Someday you gotta be the friend who covers his tracks for him. And that's a pretty high form of dysfunction. How about the ex who dumped you? Well, then you did something right?
I wouldn't know, I haven't been dumped before.
Okay, once. But it was because I was a nerd.
People. Date the nerds in your life.
