Lyric discussion by salada 

isnt the line "But when you spoke my heart sank" ?

That would fit better with the words. it seems hes talking about pretty people, but with no real personality or intelligence

"The light is on but no one's home" basically means that. and when his heart sant hes dissapointed because they arent really interesting at all,

haha its funny because this song is so sweet but the lyrics are so opposite
