Hey man, I love heavy metal music! Do you listen to it?
Hi! I have, and even though a lot of critics don't seem to like it, I appreciate it as a genre.
Yeah, it's a bit of an acquired taste. I have really long hair and shake it around when I go to concerts. It's a blast! 
I agree. But man, respect, I wish I could grow my hair to a considerable length, but it looks terrible on me!
Yeah, I might have to shave it soon though. I'm starting to loose it in the center! Either getting old or too much head banging! 
Either way, your long hair will live on in your soul, brother. Hairstyles can be lifestyles.
Yeah, what's your favorite metal band?
Don't laugh, but I think I'd say Alice in Chains. I think it barely qualifies, but yeah.
