Something big you did not forsee will happen in the next month

I was reading David Allen’s book Ready for Anything (which is a good read though you should read his classic Getting Things Done first), and one of the first articles recommends that the reader should write a note to themself, “something big you did not anticipate will happen in your life in the next month.”

I was reading it on my way to my cousins wedding and with a busy summer this year (I had another wedding on Labor Day and plenty of work in between) so I did not think anything big really could happen this summer.  As it worked out, nothing really big happened by August 16, but I decided to throw it a month forward in my files just for fun.
Well, I guess that living through a big storm, seeing a major metropolis shut down for several days, and having no electricity for a couple weeks constitutes as “something big”.
