i once saw (in a Garfield's treasury book) Garfield cat's master, Jon ask Garfield to see his girl friend who is out there (near them), but even used telescope could not Garfield seem to find her! The angry Jon shouted at Garfield: "I get the point!"

- that's what puzzled me! what does point mean?
