It's painful, longing for someone whose heart will always be out of your reach, even more so when you know this can never be changed. So my sincerest advice to you, is to treat it as a rainy day; you don't dwell on a rainy day, because deep down in your heart you will always know the sun will come out eventually. You just have to wait. I'll wait with you, for as long as it takes for the ache to subside.
