What role should friends play in adolescence?

She is very important, very important. The best state between friends should be comfortable. Make each other feel comfortable. If we don't meet for a year or two, it won't be strange to meet again. Keep a distance from each other, physically and psychologically. Don't be too close and trust each other. Only in this way can we go on and quarrel, but we won't be torn to pieces. The best love for her is that every time I eat delicious food, I will think that when she comes to Beijing, I must take her to eat. You are the most reliable, and you will be reliable when you come back.
