True, but far to many have forgotten that in a culture of "instant gratification". Hold people to high standards and you will be surprised how often they succeed. Have low or disgusting expectations and those will be met too.
Instead of having grownups looking for stable, familial relationships, we have juveniles in adult bodies who're constantly chasing the heady euphoria of infatuation. Problem is that infatuation cannot be maintained. It's just not human nature. You'll become accustomed to the woman you stayed up all night thinking about during the first weeks of your relationship, and find yourself able to lie down right next to her and go right to sleep.
