Lyric discussion by lixy_the_pyro_pixie 

i think this is about someone who is waiting for someone he thinks he really loves but really he has exaggerated this person in his head so that they sound better than they actually are(yesterday you told me bout the blue blue sky). Because he is so wrapped up in waiting for this person he doesnt notice how isolated he has become. Thats why all he can see is just a yellow lemon tree.

Pixie, you're - according to my interpretation & sadly - spot on
