The Difference Between Being Alone and Being Lonely

Aiden likes being alone. He likes watching movies alone, walking alone, reading a book alone, likes listening to music alone. But when he notices a son and his father together or when he sees a couple hand in hand. He realizes that yeah he likes being alone but he doesn't really enjoy the thought of being lonely. But maybe just maybe that'll change for 17
year old Aiden when he bumps into a boy and that said boy tries to make Aiden not feel so lonely.
