Valentine's Day vs. S.A.D.

It's that time of year again.  Be prepared for the onslaught of social media posts!

One half of them would bat their eyelashes if they could, dripping with the sappy and overly intimate details of what couples did to celebrate the Day of Love.  Complete with emoticon hearts and kisses.

The other half will be so chock full of cynicism and bitterness that you get choked by it when you innocently walk by.  Then shove a murdered cupid in your face.

Okay, I'm exaggerating a little bit.  But you get the picture.

Let's just say there are many extreme emotions being expressed around this time of year!

What's the deal?
