No eye see mall rat

Win Keong's parents work hard to give him a good life so most of the time they are not around at home to be with him. They once said to him, "We want you to concentrate on doing your best in everything that you do, don't worry about anything else, especially the money, we'll take care of it". Feeling bored staying at home with just the maid, he often goes to the mall to hang out. He just loves to wander around the mall and to look at new innovative products. He seldom buys anything because he does not want his parents to find out about this habit of his. One day, a friend of his father who has a shop at the mall that Win Keong frequents, met up with his father and casually mentioned to his father about seeing Win Keong there almost everyday. Normally, one would expect the father to blow up or to advise his son to spend more time on his studies but no, the father just kept this piece of information to himself and did nothing.
