I've never thought about it like this, but it's hard to argue with that logic.
But the counterargument there is with free travel, an ever-shrinking world and Internet options, it might be easier to find that perfect, set-in-their-ways chicka.
It's not hard to argue with that logic.
The problem is, you're young, you're in love, you share all these hobbies, interests whatever...
Then you grow the fuck up and change and don't like to do the same shit anymore. I don't like to do the shit I did at 20 anymore now that I'm 23, and I may very well may not like to do whatever I do now when I'm 30 or 40. There's too much changing going on for many people in their 20's to get married IMO.
