The best proof of love is trust.
Trust can be developed only when there's honesty.
"Truth has power. Even if I don't understand you, I will know that you're telling the truth, 'coz it will resonate within me. (Sic)"

"Honesty is such a lonely word,
Everyone is so untrue,
Honesty is hardly ever heard,
And mostly what I need from you".
- from the song 'Honesty' by Billy Joel
