I know a very kind homeschooling mother of seven who has dreadlocks down to her knees.
I thought when her oldest got married she would cut them off for the wedding, but she was the mother of the groom with dreadlocks.
Regardless, in my opinion they (dreadlocks) are still nasty. It doesn’t reflect on the character of the person who has them.
People come in all types and colors and demeanors and are creatures of habit and practice. From a practical standpoint, there is no way a mess of balled up coils like that can be adequately maintained in a sanitary manner.
