Shhh I can't be too loud

Shhhh listen I can't be too loud
These words are only meant for your ears only  
These words are written for your eyes only
I'm afraid if I shout walls with ears will start talking  
I'm afraid the meaning of these words will be lost in the echo of my voice of I shout  
Shhhh listen I can't be too loud  
These words am I'm about to speak are a reflection of my heart
Maybe I've said this before  
maybe you're lost in an abyss of where this is coming from  
Yet one thing is for certain  
"you don't know when love begins, but you know when it's already there"  
Yes, I've given myself away on that line  
Yet I think this is the best way to tell you that I love you  
If I knew any different way to express these feelings to you I would stand on to of the world and shout it out  
But I have to whisper I can't be too loud
Cause love is a selfish thing  
Shhhh listen
