Why refuse what's offered to you?

Why do people love to avoid something offered to them only to complain the next minute? What do I mean? Here's an example. You like someone. That someone knows they like you back. That significant other is always talking about how he/she has no one but as soon as you tell them your true feelings their first answer is no. No chances no nothing cause they have some bullsh*t excuse like their afraid they'll lose your friendship or your just not meant to be. Another example. When you give someone advice. They praise said advice and thank you but then come back to you a week later with the same unresolved problem. When you asked if they used your advice you get the pause indicating that your advice that was so good was thrown out the window cause everyone's a hard head trying to make you feel like you helped.

No one wants their help tossed away when you explained how amazing it was. No one wants their love tossed aside because even though the two of you are in love your too afraid of the risks being taken. Why not go out on a limb if thats where the fruit is hanging? Isn't that the point of life? Taking risks and living on the edge??? Apparently not in most people's cases.

Humans strive so much on negativitey, have discussions and arguements over it and it pretty much becomes all we talk about. It's never a "Hey, what a nice day today." anymore it's "Did you hear what happened she's such a whore, or all the talk we hear behind door's, if being positive is being rich our society is poor because all we do is dwell on problems instead of looking for more. More happiness but it can't be found because positive is covered in a shroud while negativity is the problem child screaming out loud, Like the devil in disguise as a female well endowed. Why not love? here have a cupcake, but the minute we offer we get the slap of hate, my cupcakes on the floor, peace no more, and now i shut the door, in this room becomes where my hate is stored. Show me some smiles, turn down the frowns cause when we look unhappy no one wants to be around...
