Goodwood brings up an interesting point in a recent post. My friend's husband believes that in order for a couple to 'click' and have a lasting relationship, both people need to be within +/- 5 years of each other. He cites common memories and pop culture knowledge as the basis for his theory. I don't mean this in a snobby way; but I think it's more important that both partners come from a similar socio-economic background. Usually this means you will both have the same sense of morals and ethics which is an important component in any relationship. Which is more important to you when choosing a life partner or spouse; closeness in age or similar socio-economic backgrounds? Or perhaps neither of those things figure into your checklist.
