He sends a video message to his mother --- What a touching surprise!

A woman sees a video message on her laptop in which her son promises that he is coming back home and that he is going to arrive by swimming the distance that separates them. The short video message ends with the son apparently diving into the sea to start his journey swimming back home to his mother. Obviously, his mother thinks that is a nice joke! 

However, in the video, when the mother looks out into the distance she sees a figure coming out of the sea, and realizes that the joke is not a joke at all! In fact, her son, to keep up the game, actually emerges from the sea, walks up to her on the beach and embraces his mother -- who is left literally speechless!
