I was working this other day, and I saw this elderly man struggling to hang the Singapore flag at midnight, and I was thinking to myself why he'd push himself so much to finish a job when he could do it the next day. He had a bandage over an injury over his knee, and had difficulty carrying his tools while climbing up the ladder. Of course, I offered to help with Dave, but it just makes me feel sad that he has to work despite his age and the late hours.
