But once you've learned to be lonely
And lonely is the only thing you've known
It begins to feel like home
It becomes your comfort zone
Once you've learned to be without someone
And settle for the silence of an empty room
Oh, it changes you
There's a lot you have to undo
Once you've learned to be lonely
I've built these walls, but I feel them falling down
Touch by touch your love is my way out
(from "Once You've Learned To Be Lonely," Reba McEntire)
