A glance at my reviews will reveal that I have a Ph.D in Third Wheeling. I arrived at the Chloe with two friends, and shockingly both of them were as single as me. Conversation promised to be good.
As one drink turned into another, and another, I began to notice that my friends were maybe not as single as they proclaimed.
One of them began to detail the love lives of a few of our mutual friends: he is now engaged, she is now married, they are now happy.
As my friend kept on describing the joyful romantic circumstances of the people we knew, my other friend lost all the will to live. Her face, usually vibrant and full of beauty, had transformed into a resigned and weary visage. It was all in her eyes.
"Are you okay?", I asked her.
"Everything's fine", she replied with titanic effort.
Ten minutes later we were out of Bar Chloe. I said goodbye to my friends and I thought about the interaction between them throughout all that day.
And then I knew. And I so deeply felt for her.
