Human deficiency- stories in an elevator

Have you ever met a situation like this? My friend asked suddenly when he met me in the elevator led to our office on the 14th floor. He was not wait for my words but continued to tell his problem. "You know, I love my mom so much and take her from my home province to HCMC. However, my mom and my wife can not live with each other peacefuly. Mom gets angry when I tell her what is wrong and right from the story occured between two beloved folks. Mom says that now I have a young and beautiful woman and I do not pay much attention to her. She says she needs not to stay in HCMC and insists me to send her home. Another friend, who was with us in the elevator, followed my friend's foot steps. He added, "I have something in common. I probably get a good job compared to other members in my family. However, it appears that my brothers and sister do not like me as they did when I was a student. They feel a complex when they see gifts I buy for my mom. I said goodbye to my friends but I was thinking much about a story that another friend told me yesterday. He said, this year he was a star at his office. The sales volume, he earned, was highest among his colleagues in his company. Bosses call him for every meeting and some consultations. However, the more connections he gets from the bosses, the less friendship he receives from friends and colleagues. Is there any correlation among three stories? I much do a research and tell you later.

A positive sum game

My family went to Dalat for vacation. We went to Dalat market for lunches everyday. The first day, we went to a very crowded restaurant. Waiting for the available seats, another restaurant's owner, who was selling soft-drinks, waved and offered us the seats. We got lunch and did not forget to reward her some drinks. We went to another restaurant the next day. The owner was so busy with many customers while her neighbor did not have anyone. The neighbor went to the busy one. She washed dishes, cleaned tables and delivered meals. When I asked, "why do you work for your competitor?" With a smile, she said, "Tomorrow, if I am busy, my neighbor may help me."
