One post will not display

I actually just updated to WP 2.9.2, but even right before that I noticed that one of my previous posts does not display. The post is still there, but doesn’t show up. I did change the name of the category, but I did this on other posts as well and they still display. Here’s my blog url: https://colorindesign.net. The post that will not display is: https://colorindesign.net/2010/01/18/pausing-to-ponder-pink/.

I’m a fairly new user and am completely perplexed.
