I was at a bar awhile back with some of my university friends, sharing beers and relaxing, when a homeless man approached us. He had a deck of cards, and was trying to entertain us for money. Everyone laughed him off, making the usual jokes about homeless people trying to bum change for drugs. I didn't say anything. After a few beers, I quietly excused myself. I had a curfew that night at the homeless shelter.
I was used to making exits like this. For almost a year prior, I had found ways to delicately balance my social life in college with the restrictions of being homeless, often leaving early from social outings with the excuse that I was tired or had to study, so that I could secure a place to sleep that night.
