Everything happens for a reason. At times when i took a chance, when i took a shot, you might think that i'm a bullet proof, but i'm not. I have feelings too! Everyone does. And from where you stand, you have no rights to judge others for who they are, and what they do in life.
Having that said than done, is nothing. Talk is cheap, perhaps should i say it's free. Everyone knows that. Its the deeds that mean something. But when you promise and what you said may not be entirely fulfilled or true.
Promises can be broken. Everyone has heard of that. It's true, loving someone and just saying 'i love you', do mean something when you say it from the bottom of your heart. But it really takes a lifetime to prove it. And believe, in life there's always the good and the evil.
