Hi - Please see my edits in bold below.
Introduction of my friend
Good morning, ladies and gentlemen. Today, Iíll introduce you to a friend of mine.
When I first saw him, I thought he was so funny. And when I first heard his name, I imagined KFC's Mini Burger. (You know, KFC's cheapest hamburger.) He shares some common features with the Mini Burger. So can you guess who he is? Yes, heís Sam.
Heís not tall and fat, so heís a "Mini Boy".
Much like how the meat patty of the Mini Burger is protected on both sides by the bread, so is Sam. Heís introverted and shy. Seldom does he speak to other people, especially girls in an alien environment. He has a strong sense of self protection as well. He won't risk going to a dangerous place or playing with unfamiliar people, as he knows heís necessary to his family, teachers and friends. Heís full of concern for his safety.
The meat patty is to the Mini Burger what principle is to a man. Without the meat patty, itíll be tasteless. Without the principle, the man cannot be called a man. As the saying goes, being smooth on the surface, but firm at heart is an important interpersonal skill. Heís sure to practice this skill. Toward most things, heís tolerant. But his principles cannot be broken by anyone. For example, he will never cross the road when the light is red or jump a queue, no matter how long it is. Moreover, you donít need to worry about if heíll owe you money. He doesnít owe anybody anything.
But whatever happens, one thing will never change-his hobby of eating the Mini Burger.
