LOL, I was finishing my monography and dating it, then instead of 2005, I wrote 2001! Can you believe it? I was 4 years back in time, have you ever done that? It wasnot a typo, I was distracted lol. I had done it b4, but not 4 years, usually just one or two. *sigh*
And it's happened that I have forgotten the year I was in b4, like, I got totally lost in time and space lol.
