Before my recent graduation, the last project of the term was called “Smile”. The class was asked to go out and 36 at three people and record their 37 . Soon after we were given the 38 , my husband and I went out to McDonald’s one cold morning. We were standing in 39 , waiting to be 40 , when suddenly everyone around us began to back away. A feeling of 41 rose up inside of me as I wondered what happened. As I 42 around I smelled a horrible dirty smell. Behind me were two poor homeless men.

I graduated with one of the most important 55 I would ever learn, unconditional acceptance.
