Return to Sender by Elvis Presley

I know this song is from "Girls, Girls, Girls" which is an Elvis move (one I have not seen), but the more I listen to it I find there to be some sort of message and it's not just for the enjoyment, which is basically what most or all of Elvis's songs were for.
The message that I get from it is actually from every man who has made their girlfriends mad and then they try to say sorry over and over again, but the girl doesn't want to forgive them.
The message is basic, but not all songs have messages and not all messages are deep and physiological.
