Today our phrase is "have nothing in common".
This means to have very different ideas or interests.
I have nothing in common with my co-workers. They are all in their mid-twenties and I am fifty something. They are all staunch Democrats and I am a Republican. So, it's hard to have a conversation with them.
It's important to find someone who you can get along with, if you want to get married. If you have nothing in common, it will be tough to make it work.
