Hat Knobs

so i was sitting in with my friend in his brothers car and his brother was working on the car so the hood was up and we had the radio on and we were just talking like normal and this song came on (spending all my time by aaron fresh) and i said hey turn it up i like this song and he was yeah? me too and i reached for the knob to turn it up and so did he then his hand was on mine and he turned it with his hand over mine and then we were just talking again and my sister text me half threw the song and told me to come meat her i told him that i should probably get going so i said bye and he said wait and i turned around and he kissed me (this was both of ours first) and then when it was over i said ok bye (his name) then i got out of the car i said his name again waiting for a good bye and he was looking down biting his bottom lip and touches the brim of his hat in his lap and he looked over and said oh yeah bye what does this mean?
