My thing about parties is this:
1. What's with the super loud music? - I like music just as much as anyone, and I have a good audio system that can rock, but my point is, if people are getting together to socialize and thus presumably converse, why do they play music loudly, resulting in everyone simply yelling in order to communicate? Bradley mentioned loud music, and I agree - it's usually way too loud.
2. Smoking - This is the number 1 reason I never took to the bar scene, and never will. I was out last month at a local hotel/bar for Karaoke and the smoke was stifling. I came home reeking to high heaven. Yes, I know that smoking is a social habit that goes hand-in-hand with drinking and such, and that's why I don't frequent such places - the smokers win. I give up. If I were single, I'd choose some other way to meet people. The same can be applied to parties too, again as mentioned by Bradley, and I agree with him on that too.
I was at a neighborhood Halloween party, held virtually outside my back door. Luckily, we were outside, thus mitigating the effects of smoking, and not many smokers were there anyway. The music was loud, but again, being outdoors helped. Still, we all had to talk loud to communicate. But overall, not a bad gig and fun overall, plus my first Halloween party (did not dress up though).
