So I was practicing upstairs out of the basement today, because I need to practice some stuff with an MP3 and needed my big computer speakers. I was only going to practice two and a half hours, but some neighborhood kids were heckling me, so it went to three and a half. Wow, the last half hour was all loud, obnoxious, peircing high notes! Anyone else have this problem? What do you do?...I went and told their parents!
