I think Gene Kelly is a happy person.
In the beginning he is like a gentleman because his wife is with him. At first you think nothing is happening there are only two persons and they are kissing. His wife is just saying that the rain is so much today in California so he should take the umbrella and go home quickly.
But when the wife closes the door he is starting to have fun. He is like a “little child playing in the rain and singing”. I think Kelly used a lot of space in the video. First, he was dancing along the sidewalk for about 1o meters and he is doing tap-dance. Is that cool or not!? He is using lots of props, he danced around the lamp and he jumped up and down in the water.
He went onto the street and danced with the umbrella.
But now the police man is behind Kelly and he is a normal person again. He is closing the umbrella and is giving the umbrella to the men who is walking there and the funny thing is he is always looking back to see if the police man is following him.
And here is the link if you want ton watch the video :
