Today is a day dear to the heart of all English teachers. Yes, it's (drum roll, please)...
NATIONAL PUNCTUATION DAY!
First of all, YES, there is such a day. In fact, today marks the fifth anniversary of this blessed celebration. And to encourage all of you in the noble pursuit of correct punctuation, here is the official web site.
So, don't party too hearty, k? We still have teaching to accomplish tomorrow.
