Imagine B walking down a runway shaking their hips and moving to the beat of the song that is playing in the background. Person A walks by B and is very confused what is going on. B starts to sing the lyrics and twerking. B doesn't know A is there and just dancing their heart out. 

A coughs and B stops dancing and stares at A for a while. 

A says, "keep dancing, I like it." B smiles and starts to dance again.
