An old van

My car broke down in the middle of the highway in a completely unfamiliar place.  Everyone was driving by, and I didn't know what to do.  My cell phone was not picking up a signal.  Just then an old van stopped, and an elderly man got out. He said he knew how to repair cars and could help.  I doubted it, because the van looked even worse than my car. But he quietly opened the hood, touched a few wires, and after a few minutes said I could go.  It turned out to be a simple battery problem that I hadn't even noticed.  The man never said his name, just wished me luck and drove away.  After that incident, I realized that sometimes you can meet real angels on the roads.  I was already desperate and didn't know what to do on the roadside with a broken down car and no cell phone service. Fortunately, everything went well for me. The only thing I was worried about was my girlfriend. we always communicate with her on this site and I couldn't answer her. It made me a little worried.
