Working of the delete keyword

It says on here thst deleting a pointer pointing to some object of a class will destroy the object but that’ll only happen if the object is dynamically allocated right? Why would a normal object be destroyed if we delete a pointer pointing to it?!? Won’t just the pointer be deleted, and the object still stay there?

When delete is used to deallocate memory for a C++ class object, the object's destructor is called before the object's memory is deallocated (if the object has a destructor). If the operand to the delete operator is a modifiable l-value, its value is undefined after the object is deleted.

The delete operator takes a pointer to a primitive or an object. Without a pointer, it wouldn't know what to delete. They can be overloaded, so it doesn't necessarily have to be real dynamic memory.
