Someday we'll get married , and we have kids , and we got to work hard and harder to raise them . Our kids will grow up , and they would ask anything from us toys , clothes etc etc . We feel tired but in the same time we happy . They would leave us for colleges , they will work hard for us . And there would be some ehemmmm I mean many wrinkles on our face . Our hairs changed to white , and you know we will gone anytime . Yup , we - humans .
