submarines sound P1

Oliver is trying to find his personal purpose as he believes that everyone has a purpose, with the non-diegetic music's restlessness and busy nature it really helps us understand his mood and feeling over what he is doing. 
The aldonte tempo (walking speed) gives a mellow feel to the clip and keeps everything calm so its like his thoughts are just casual and what he does, not that hes in a bad mood hes just letting the girl know how to avoid being bullied as he feels bad for her. he wants to help the girl and with the calm music we can tell that he is doing a more heart to heart kind of letter to her, and that he doesn't mean and bad feelings.
