A recent case became popular in my country which made me wonder how can you distinguish crazy (the nut head level) from the ones that have delusions but acceptable. And then it just occurred to me that would depend on the crowd of men she would hang out with. If the guys she is hanging out with are jack shit crazy with no integrity, chances are high that the girl in question is a country of red flag and sleeps with it, but if not (say someone like Michael) then chances are that it won't be on the lower to mid range of the delusions.
