Imagine if this goes on till they get married and still work at the same place.
"what, you married my long lost brother so we have the same surnames? What a coincidence!"
"What your pregnant? That's great! I wasn't supposed to tell anyone but my wife and I just went to the doctor and it turns out my wife is also pregnant!"
"She's adorable! And she can already say 'papa' impressive! Although I don't think she knows what it means. I should bring my girl too so they can meet up, but my wife is wierdly set against ever meeting you."
"We should really stop having this affair. We both have our own life's, we've both become parents and should start taking responsibility for our actions. I'm gonna come clean with my wife, Im pretty sure she's also been cheating on me and I hope to discuss how we can move forward in this mess together. So let this be our last night together, please."
