Familiar strangers

When you go to a place to work, you will meet a new group of people, but also meet a very good play of people, we call it girlfriend, you will go shopping together, chat and eat and drink everywhere, think that she is the person you can't do without in your life, but as long as you change a place, the contact will be less and less, gradually, you will no longer contact, and finally become the most familiar stranger. Obviously, I still remember a lot of things, but I can't remember her appearance more and more. Sometimes you will go alone to the place where you have been, take a look, and even make silly music, but when you really pass by, no one has the courage to greet each other first, there is a good saying, a lot of parting, is forever. Obviously, when they were separated, they were so reluctant to do so. Always look forward to the encounter, but after the real encounter, the difference is the courage to stretch out the hand. It wasn't until many years later that you had forgotten what the other person looked like. When they meet again, they are already strangers.
