I have four problems with clubs:
1. The music is hardly a music. Club music that deserves this name ended in the 80ties, and it was already borderline. Now we have noise.
2. Even if the music would be proper, DJs are awfully incompetent. The music so loud that it's uncomfortable, may cause a tinnitus, and any music cannot be listened because all the audio is badly adjusted to the room, and volume level is too high, so so tones turn into sounds of undefined pitch.
3. I just don't like it, there is something unpleasant, inelegant and almost disgusting in most of them. And I'm an atheist and really don't mind other people's preferences. I just dislike certain places, sounds, voice modulation etc.
4. Even though I'm 26 I still look like 17 so always have a feeling that I don't fit to company that can be found out there. People of my apperance are too immature, and I look like a teenager in comparision to people of my age.
