Cover art for The Bolder Thing to Do lyrics by Gregory and the Hawk

basically, she's the second girl in his life. she knows he is in love with another girl and is just passing his time with her until he can be with the other girl again. she can't let him go and is fighting to win him over, but no matter how much she tries he just breaks her heart more. and instead of making a big scene she'll just remember what he did to her.
