You got the wording right, the meaning wrong, this is the true and correct version.
There are a few ‘special’ girls (not quite sure why these are special), most of the rest are just plain ‘good’ girls. To some it came naturally, to some hereditary and to a select few others they actually worked on themselves. These are all good girls, good middos, good looking, good personality, good acting, good sisters, will be good mothers, just good, there is nothing wrong with them, but it is true an odd few girls get singled out for a particular ‘maalah or two’ that they have. Being that there are so many ‘good’, yes, really good girls out there sometimes makes them seem abundant and excuse the expression, a cheap commodity. These ‘good’ girls sometimes become the best wives possible.
