Hey Guy:
You will have a great blond beard in no time. I hate it when barbers do the wrong thing. He should have asked you what you were doing. I would have been really angry if it were longer. But, you have a little time, and I can see where it is supposed to be now. I would leave the neckline and then do a neckline later. Nice stache and soul patch also to go with your chin also. You will look more mature for sure. Keep growing. Tom
