Welcome back and congratulations on the new job! Glad to hear that being long-bearded isn't an issue for a school teacher. It's a great example to set but, then again, I may be a bit biased in that comment.

Don't worry about the lack of growth under your lip. Many guys have that pattern, and some even shave the area to get it. Also, at 24, your beard still probably has years of development ahead, so the area may fill in with time. In the meantime, enjoy the beautiful beard you've grown already!

Cheers!
Tom
