The last time I cried was Friday afternoon as I was talking to two of my friends in Skype about my cat's death from the day before. The way I worded some things was just so utterly depressing for me to read and I just lost it.
Normally, though, besides this year, I only cry once a year as I've noticed: Once in December, 2006; once in June, 2010; once in November, 2011; and then March 15th and 16th, 2012.
