Having spent far too many NYEs in the past helping "people" (not sure all of them were actually humans!) get poofaced and/or picking up the pieces when things went breasts aloft, we now stay in and ignore the whole shebang! If (by some weird chance) we happen to be awake at midnight, we'll wish each other a Happy New Year (hell, it's GOT to be better than 2012!!!), roll over and go back to sleep (after reassuring the cat that the nasty bangs will stop soon).
I'll spend a little while tomorrow writing 2013 in the chequebook before heading out to pick up the MiL who's taking us out for lunch at a very nice pub a few miles from her place. Well, we're taking her out since she doesn't drive but lunch is on her. Nice long, straight hill on the way - my wife reckons a touch over the ton before MiL realises we're pressing on a bit, conditions and other users permitting.
