What are some things that will fade out due to coronavirus?

As time has gone by, past sayings have become meaningless. “Drop a dime on someone” referred to dropping a dime in a payphone to report someone’s wrongdoing. Kids today don’t understand what it means and probably have never seen a payphone. With the current changes we are seeing in society due to the coronavirus, what sayings or activities could become meaningless? The first one I thought of was “you have a lovely smile”. Humor is welcome.
