..eyebrows that meet in the middle.

There's nothing worse than eyebrows that meet in the middle. In my youth, in East London, it was a well-known fact that adolescent boys that had eyebrows that met in the middle would grow up to be criminals. Mothers would tell you "stay away from the boy in the corner house - his eyebrows meet." As a thirteen year-old, any sign of the eyebrows being joined by adolescent hair had to be dealt with using dad's razor, and then it became a twice weekly lifelong job keeping it away. I suppose tweezers would have been better, but that was a bit of a girls thing - boys don't really have the skill set to use a pair of tweezers.  If you need proof of the eyebrows theory for men, just look at old Bill Sykes. Obviously, and this doesn't really need saying, girls with joined eyebrows will never get married.
