Dear Non-Existent-Ex-Boyfriend,
Again, I am caught in this awkward situation. What do I even say? Sorry that you don't exist? I clearly wasn't thinking when I took this letter-writing challenge. Well..... whatever I imaginarily did to you, an imaginary being, I apologize. Okay, awkwardness done? Okay? Okay? Okay.
Imma go now. Have a nice imaginary life!
Love,
Kirsten
