Welcome! I don't feel angry (or even isolated, exactly), but I don't know many vegetarians (let alone vegans) in real life. So I come here a lot.
I love all kinds of music, but my favorite is classical- from Renaissance to Impressionist, with even some of what I would call modern (Aaron Copeland, Randall Thompson...). I also like classic rock, oldies (60s music), some country/western, and maybe bluegrass and jazz (I'm just starting to explore those last two). I've seen both Robert Plant and KISS in concert (different days!). Plant did a number of Led Zeppelin songs; I had to leave the KISS concert before Gene did his fire-breathing-blood-spitting thing, and neither Ace nor Peter were with the band at that point (ggrrrrr). But it was all good. Def Leppard was playing right before KISS, and I had really gone to see them primarily.
Edited to add: WHOA- I just went back and noticed you're 13. Impressive! I didn't even become pescatarian until I was 16. People have been accepting of my care for animals, but unfortunately, they generally haven't followed my example as far as diet goes. You're learning about nutrition, right?
I taught myself some (acoustic) guitar but didn't take lessons, so I'm still a beginner there. I did study classical piano, but don't practice enough since I stopped taking lessons. And I always had trouble playing anything fast (like the last movement of Beethoven's C# minor sonata for piano, popularly known as "Moonlight"- what a finger-buster!- I think I played it at only about 1/10th the correct tempo).
