Cover art for Smash lyrics by Goo Goo Dolls, The

i have no clue what the song means. i'm going to guess and say that it's about a relationship with bad communication(she never talks to him about how she's feeling) and she's trying to hide her depressed feelings. but they still love each other. i have no clue what he was thinking when he wrote this one.

oh, and maybe 'smash' is referring to when she becomes sad and depressed again.
