Is it irony or have we actually merged into one person?

After lunch, typing away on our computers before our afternoon class, Kyle turns to me and says, "I feel like I am getting a fever blister."
"Where?" I ask
He points to the corner of his lip, which indeed looks agravated.
"You should go see the nurse" I advise. (Because we are at an English Village where the kids stay day and night, there is always a nurse on hand who gives medicine when required.)

After a few moments, he says, "It says here," looking at his computer screen "that sometimes a cut in the lip can feel like a fever blister. Maybe I will wait till morning."
"Sounds like a plan." I reply smiling at his cautious nature.

The next morning, as the annoying beeping of the alarm awoke us, and the first yawn graced my lips I realized from the burning sensation on my upper lip, that in fact I had a fever blister.
My eyes pivot immediatly to where Kyle had pointed previously. " Do you have a fever blister?" I demand.
"No, it must have been a cut." Kyle says with relief
"I never felt like I was getting a fever blister so how did I end up with one and you didn't" I implore without actual hope for an answer.

So there you have it. Is it irony or have we actually merged into one being with one feeling the others pain?
