POST 136: "When I say "more than 3 months" it doesn't mean, exactly 3 months. It means longer than a short period of time so that you have a pretty well established idea as to who he is."
someone can't read...post 136 is irrelevant to the point. Pick any number you like: 3 months, 6 months, a year. (I guarantee if you start at a year at 14 it will be down to a month by 28, so you can factor that in, as well.)
