【正确答案】
It's quite a natural thing that someone is attracted by tile person whose thought, faith and interest are similar to his. Equally, getting along with those who have similar characteristics of appearance with you makes you feel comfortable.
You may have noticed that people getting along closely with each other in life and work tend to be similar in behaviors. We will often imitate those we approach, love, or admire unconsciously. Therefore, the football fans will imitate a certain athlete's unique way to walk with shrugging shoulders; even a pair of lovers' way of shaking heads is same. The employees will imitate their employers' habit of playing with a pen among fingers while pondering over a question.
The influential persons aren't aware of this kind of imitation in all situations consciously, but the existence of this imitation will make them feel comfortable. He will be glad if he indeed notices that others' gestures or movements are identical to his. Because that means he has exerted an influence on others and thus he is attractive to those people.
