Unsuspecting Woman Feels Left Out of Friend Group, Finds Out They're All In a Polyamorous Relationship

The agony of being the third wheel is a well-documented one. I actually consider myself to be a professional third wheel. A professional tricycle modification, if you will. If I want to hang out, I'm going to hang out - relationships be damned. Not everyone has such an agreeable position regarding hanging out with people who are involved. And I get it. There's the PDA, the inside jokes, the baby talk. It can all get pretty unnerving. But trust me when I say that it could be much, much worse.

Twitter user @LBPluvr shared this grievous alternative to third wheeling a few days ago, and it's…giving pain.

OP shared that she had been feeling very left out within her friend group, and that apparently it was because they were all in a polyamorous relationship. While transparency is generally appreciated in times like these, we're not sure if this is an “ignorance is bliss” situation or a very awkward "Eureka!" moment.
OP's disbelief at this unfortunate reality was echoed at least tenfold by her followers, whose abject horror took the tweet to viral status. It's racked up over 400k likes since being posted, and a whopping 23k retweets.
While we in no way delight at @LBPluvr's situation, we have to admit the responses have been entertaining. At least OP seems to have a bit of a sense of humor regarding the matter.

Jokes and cautionary tales aside, sometimes the most astute and powerful reactions are the simplest:
