The Great Believers by Rebecca Makkai:
The next day, Saturday, Yale went to the movies. He saw Spies Like Us and Out of Africa, but they weren’t as distracting as he’d hoped. He was more absorbed with the people around him, the couples and teenagers and solo film buffs having perfectly normal days himself. It seemed such an alien concept now, to have a normal day. To walk around oblivious, just participating in the world. It seemed unreasonable for anyone to be allowed a normal day.
