Can friction exist between two objects that are not in contact

If you find two objects at rest even when an external force is applied on it then it means friction is acting on them . Had there been no friction there would have been relative motion and the definition means that this motion will be opposed by friction ( if it happens to exist ) .

Explanation:

The frictional force is the other component; it is in a direction parallel to the plane of the interface between objects. ... When a frictional force exists but there is no relative motion of the surfaces in contact (e.g., the book isn't sliding across the table), we call it a static frictional force.
