Hola Alberto:
Can it be 13 weeks??????? Wow! I am glad you decided to keep on without trimming. I think your beards truly are coming together. Especially when you look at the underside, you can see that the colors are becoming one. I believe that a trim would take that away. You have several unifying things. Your mustache is so nice, and the area under your mouth is really nice. Your chin is perfect and becoming longer. The rounding is what is called "bulk". So, your beard is bulking up. So, now just relax and let it all continue to grow, as you grow inside.

Thanks for the update. I was waiting for you.
Grow on.
Tom
