Sal moved into my apartment while I was in my sophomore year of my education program (aka: my third senior year). He was practically living there before he officially moved in, he just had a laundry basket worth of stuff still at the apartment he shared with his friends. Due to this, I felt no need to introduce him to anything in the apartment, figuring he already knew it all.
One day I was sitting on the couch writing a paper while he was cooking, across from my office. When I finished, I sent the paper wirelessly to my printer. Since it tended to take a while, I didn’t bother to get up and checked my email instead.
Suddenly, Salvador came running into the living room. He had a panicked look on his face.
“Come quick! Something is happening to your paper!” he cried out.
“Yes, honey, I know. It is printing.”
After dinner I introduced him to the printer and he found the thing awe-inspiring. Not all that much later I would be walking around Mexico with the same look of wonder and confusion on my face.
