Yeah, I think that I'll let the back get a bit longer and then I'll get the front/sides trimmed so that it doesn't look too haggard. Besides wanting to have the "business in the front" look, it gets annoying when the front gets too long, because the hair sometimes gets in my eyes.
I think part of the reason people don't say anything to me about it is because I'm currently residing in a part of the world where the mullet haircut is still very popular (Russia, that is), so what I have is considered a pretty normal haircut here, even though in other places it might be considered a major fashion crime.
