We live in interesting times . . . and apparently, these days, we're a lot less likely to "laugh so hard we cry" and more likely to just cry.
According to Emojipedia, the number of people using the "tears of joy" emoji has plummeted since early 2017. That's the emoji that's laughing and has tears coming out of its eyes . . . and it USED to be THE most popular one. Not anymore.
No one's EXACTLY sure why it's fading, though. It could be these depressing times . . . it could be that there are more emojis than ever to choose from, so people are getting more creative . . . or it could just be that emoji fads come and go.
