I have a friend and most would say, she is not very attractive. Her man is drop dead handsome. He only has eyes for her...he sees her in a different light.
Or he sees her thru the eyes of Bud Light. :)
No one can say: I am not good enough, pretty enough or too old.
Well, one can say that -- but I think the thing is, as you point out, is that there are no Absolutes. You look on a graph, and it's Pretty Steady when it comes to people who don't otherwise know each other on looks vs looks in the same league to land productive dates, etc. But there's always dots off the mark, always some small %. One just has to look at it like having a Low batting average. Doesn't mean you won't get a base hit. But if you only go up to the plate once in a Great while, it'll be Forever until you get a hit. Realizing that should be motivation to improving oneself, which over time will increase their batting average to something better, too.
