The Sweetheart Tango Sweetest day animated ecard begins with two hearts on a stage in the dark waiting for the lights to come on and when they do, the male heart wearing a bowtie and shoes invites the female heart holding a flower in her mouth and wearing heels, to take his hand. They then proceed to dance a tango on the stage doing amazing moves and smiling at one another. At the end of the dance, the male dancer brings his partner backwards close to the ground. She looks out of breath as he smiles and the final banner reads “happy sweetest day".
