On the way back from work every evening, more often than not there would be a homeless man standing at the exit of the freeway  . He looked to be in his late 40s but was probably a lot younger. He had shoulder length straight black hair and a short beard. Every day after work I would remember to gather any spare change, and put it aside to give to him if I saw him. A feeling of joy would come over me every time I saw him, while coming off the ramp  . So did he. Sometimes the red light would be on for a minute and we would ask each other about our day. His answer would always be the same, "I'm blessed!" Then one day I was called into my boss's office and was told that I was being laid off. For the rest of that day all I could think of was "how am I going to provide for my kids as a mother, how am I going to pay rent?" Needless to say that on my way home that day I was very sad and upset. I didn't remember to look for my spare change and keep it ready like I usually did. Yet there he was as always, as I turned the ramp. He set his eyes on me, while still smiling and waving at others as usual. While I was waiting for the red light to turn, he strolled   over to my car. He had a big smile. He looked at me straight in the eyes and said, "Today I will give you a dollar." He then reached into his pocket and pulled out a dollar bill. You see that day he taught me a valuable lesson more than a dollar bill. No matter what material things are taken from you, no one can take away your choice to be joyful. Every time I'm faced with challenges, I think of the homeless man's valuable lesson and remember that I am blessed. Why did the writer feel sad and upset after out of the boss's office?
Because she was criticized by the boss. Because a new job was offered to her. Because she was laid off by the boss. Because there was something wrong with her job.
