I got the concept of remaining silent when you realize you have feelings for one of your best friends because of fear of messing up the friendship a few days ago. I wrote it last night at the tropical imagery came about from there (most likely because I was listening to Zac Brown Band's "Jump Right In" while writing this). It is something special to have those feelings for a person you know so well... now if only I was 150% sure the feeling was mutual...
