Sorry about that :X2011
When I saw that this thread was inactive for 2 days after the number 2003 had been posted, I tried to wait for another member to post the number 2004, so I would be able to post my favorite 2005.
But, now I'm too late for the decade 2001-2010. All the years in this decade receive likes from me, and more especially, 2005, 2006, and 2009 receive loves.
In addition, though I posted 2000, I prefer 2001 because I always consider 2001 the first year of the new millennium
