Formula for dating age difference
But it was The Ragbag who pointed out that this rule has a duality: for the date to be socially acceptable, the rule must be adhered to by your date as well.
I know many brilliant, mature people who aren’t old enough to rent a car.I was having breakfast the other day with a friend who was giving dating advice to his son.For purposes of his anonymity, I am going to call just call him "Son." My friend said, "Son, you're 18 years old, so I am going to tell you how you date.It’s too bad O-Town was hit by a bus."He was the only "younger guy" I’d ever gone out with, by about six years, and I used to ask my friends obsessively if it was "weird." But they just thought it was strange that all of our conversations could start a potential death rumor about Ray Liotta. Ultimately, it wasn’t that this guy was young; it was that I had absolutely nothing to say to him that wasn’t "There," "Not there," "NOT there, this isn’t anybody’s birthday," or "Slow down, Usain Bolt, who incidentally is A lot of us have found ourselves attracted to somebody younger or older, and have been reluctant to act on it because of some perceived weirdness or taboo.Some of us limit our potential partners to a very specific age range because that’s what we think we’ll be attracted to.It's because of this urban legend that has gone around forever.
Based upon this rule, the only time that a man can date a woman his own age is when he's 14 years old (because half of 14 is seven, and seven plus seven is 14).
As Society Marched On, this became less and less the case, and in modern works a very small age gap is often considered ideal, with a maximum allowable (as opposed to "ideal") age gap proposed, and often applied equally in either direction (older man vs. One commonly-applied formula is the "half your age plus seven" rule, in which the older partner's age is divided by two and then increased by seven to reach either the ideal or minimum allowable age for a romantic partner.
Traditionally, a man was expected to be established in his career and lifestyle before marriage, whereas a woman usually transferred directly from her father's household to her husband's within a couple years of reaching adulthood, so it was considered ideal for the man to be at least somewhat older.
So the ripe old age of 14 -- the age when you still have pimples, are as insecure as can be and are unlikely to get anything more than a kiss from a woman your own age -- is the only time when you can enjoy dating a woman your own age? Add seven to that, so you can date a 12-year-old -- an older woman"?
What about if your 10-year-old looks at you and says, "I'm ready to date, Dad"? There is so much a 12-year-old can teach a 10-year-old -- advanced coloring, advanced texting, and so many other important life skills. You're 20 years old and, under this rule, you can date a 17-year-old. There you are in college, and you get to go back to high school again to find a girlfriend.
