What is the difference between an intelligent person and a wise person?

I am sitting at a coffee shop.

I am taking some time to myself before the client arrives because I have a meeting in an hour. A couple is seated directly in front of me, they are so close that I can see the wallpaper on their phone as well.

I have no doubt that they were enjoying themselves. They appeared stunning and incredibly elegant as they held hands and giggled.Anyway, there wasn’t a lot of rush at that hour and we were pretty much the only people along with a few waiters.Suddenly, the girl bangs on the table.It was so quiet that it felt like a bomb had dropped. I didn’t look up. I wanted none of them to feel embarrassed. So I keep staring at my coffee's artwork.As the argument grew more heated, the girl began yelling.

The man has not spoken yet. He appears disgusted and angry, but he is very different from a girl.I am not sure what the argument was about, but this is what I interpret it to be.

"An intelligent person knows so much that it knows nothing, leaves you hanging upside down, mouthing knowledge as your heart falls out of your mouth - Anne".

But,A wise man knows when to use his intelligence. He knows when to be silent.To me the guy is wise. He could have said anything and made the scene more dramatic.Instead, he thought one of us should be silent and since she is not I will be.

It’s hard to be a wise person. Intelligent anyone can be.
