Because in the past, if you stayed in your own small circle and didn't have any communication with other people, you might never leave order, because these are your only friends, and friends who are too close can't be lovers.
Or even if they become lovers, they may be separated later for various reasons. At this time, if two people are cutting off contacts, then there will be fewer friends around them, and some people hide in their own small circles just to avoid communicating with others. In this case, it is wishful thinking to want to take off.
However, I will know more people when I get out of my own safety zone. Facing all kinds of new friends, I will have more choices, and I may meet my true love. But it also depends on fate, because I have many friends around me. Although they have a wide circle of friends, they have always been single, just because they have not met the person who makes them move.
Moreover, young people nowadays have always maintained a quality-oriented and lightweight attitude when falling in love, so even if they don't stay in their own small circle, their eyes will not change. No matter how good a person is, as long as he doesn't like it, he is not willing to take off the bill.
Moreover, the wider the circle of friends and the higher the horizon, it may be more difficult to get rid of the order than people who have been staying in their own small circle.
