complete vs finished !!!

No English dictionary has been able to explain  the difference between the two words - 'complete' and 'finished'  in a way that's so easy to understand: Some people say there is no difference  between  'complete 'and 'finished '  but there is: When you marry the right one, you are  COMPLETE.... And when you marry the wrong one, you are  FINISHED..... And when the right one catches you with the wrong one, you are ... COMPLETELY FINISHED !!!
