I have a younger brother who just graduated from the college entrance examination. He talked about a girlfriend who had been with her classmates for two years.

This situation is out of control! The more parents object to them sticking together, they simply stop interfering and let them talk to a certain extent, because these two young people are not self-disciplined and will certainly not listen to their parents' preaching. Finally, I hope they will wake up soon! It's time to learn something real!
