I'm not looking forward to having to write '2013' or '13' when writing the date next year. 13 is a shit number. Might switch to roman numerals instead e.g. 12/02/MMXIII or could just leave it out altogether as you'd have to be a right jake to not know what year it is.
I'm also not looking forward to the end of the month as something awful I can't talk about is going to happen.
