I'm a serious person. I'm also often a literal person. In the past this has led to me hunkering down on April 1st: not communicating or interacting as much, because I want to limit the chances to be fooled. I'll have plenty of non-fooling things to do today, anyway. I don't wish to be distracted by foolishness.
This has been a serious post.
P.S. As I added on Twitter, "If you use April Fool's Day as an excuse to be a dick, Wil Wheaton will be very, very disappointed in you."
