At this time, almost everyone has returned home from work, gathering at the edge of the family. After that, they together go shopping, to entertaiment centers and parks to relax after a hard-working day. With me, Hanoi is a great place to live and work. At night wandering in the streets of Hanoi, the smell of milk flowers along the roads makes the soul become strangely peaceful. In the near future, I will build up my own beautiful house there.

Some years ago, my husband and I travelled through a small town in Italy near the Alps. We had not prepared ourselves with even a passing knowledge of the language. Young people in jovial spirits walked beside us, many with colorful scarves around their necks for warmth. One girl snacked on olives from a glass jar while another sipped wine from a bottle as we would sip Coca Cola. We ambled through a cobbled street lined with shops and searched for gift ideas to bring back to our sons. Entering a small shop which offered sports apparel, the language barrier hit us squarely. Using gestures and minimal English, I tried to communicate our wishes. The savvy shop keeper immediately lead us outside and grabbed several young boys, all the while expounding to them in Italian our predicament. With raised eyebrows she questioned if this child was similar in size to our sons. Returning to her shop, the good-natured boys served as mannequins for several soccer shirts until we made our selection. We bought two shirts as the boys smiled, waved and returned to the street. To this day, our now 40-year old son remembers the shirt emblazoned with the name of an English soccer team for which he has become an ardent fan.
