Why is it still such a big deal? I'm sure it was different before 1999? You might have gone out to your usual haunt,or had a party yourself, whatever. Or you may have stayed in with friends...or even god forbid chilled in front of tv.
People would ask if you were doing anything, you'd answer. End of story. Now you have to make an effort, people have actual opinions about the subject. 
Before the Millennium you didn't have to pay to get into every damn pub, club and shithole, nor did you HAVE to be doing SOMETHING.
It doesn't seem to be about friends and family anymore and having a nice time, it's just about doing News Years Eve.
Or have just become a miserable old gimmer in PJs with a laptop?
