In the first year after graduating from college, I became a mistress. Some people were envious, while others said that I wasted educational resources. To my parents, I was just a mistress, not a third party. They thought that a mistress was selling love with a clear price tag, which was in line with the principles of transaction. They thought it was not good for a third party.
How to say it? Strictly speaking, Mr. Wu had an ex-girlfriend, but after the breakup, he had no intention of looking for her again. Why wasn't I promoted to girlfriend? The reason is very simple. The girlfriend wants to tell everyone that she has a marriage partner and does not need to introduce him to him, but the mistress does not need to tell others and still accepts introductions from others.
That is, the difference between a mistress and a girlfriend is just whether or not they tell others.
Just like what Socrates and Plato said, it is always necessary to clearly distinguish the difference between sex and spirit.
