If you can find a really great friend or crush in such a small sample of people, there are probably millions of better or perfect ones out in the world, amirite?

For my friends it's more about everything we've gone through together a bond that's been forged not just random compatibility

But your limited sample size will likely not change that much, so the chance of finding the one is about 1 in a few hundred million.

Exactly

Sometimes that's all you need.

That's why a lot of couples break up nowadays. Because you always have the feeling that somewhere out there is someone better for you.

Casual friends are easy to find. A really great friend/crush is harder to find, big or small places and not all that replaceable.
