Kids VS adults

When we were kids, we went to school and home in the same area. We lived with our parents and siblings. We studied the same textbooks which taught us the same thing in the same class. We took the same exams and aimed at the targets. We wore school uniform and made little difference to the teachers. We were so alike. More importantly, we only did things to make ourselves. We defined happiness with the same definition.

When we become adults, we go to different homes after work in different areas. We see our partners or pets instead of parents and siblings. We work at different companies which make us having different identities. We still take exams but aim at different targets. We wear clothes in order to stand out from the crowd. We want to be distinguished from our colleagues in our bosses' eyes. We are so different. More importantly, we do things to make somebody happy. We define happiness in our own ways.
