You hear the words, I love you. But you're questioning rather they means it. To you they are spoken, but seems like love's so empty. That they don't mean a thing. Just words going the emotion of speaking. But missing the true meaning.
We know when they are real. You feel it. You enjoy it. But love so empty is exactly that. So fiction. Many many facts.
Anything fake can't be accepted. It's just an imitation of truth trying to fool you.
