It's conformers vs. non-conformers.
If you want to look different go ahead - but don't be upset when people single you out.
I can't stand it when I walk down the street and stare at some poor soul with a blue mohawk and 11 facial piercings - and he/she gives me a "wtf are you looking at" look. Gee, I thought that's what you wanted, was for me to stare.
Underlying every social setting/situation are a set of informal rules which dictate the appropriate behavior/dress/speech etc. - it's called etiquette.
Finally, for all you young bloods still in the pre-all forums, just remember that each one of us tie-nazi SDNers will one day be tie-nazi attendings
