Why do we put up with boys?

Boys...we never choose the right one, until we lose them. When we never knew that we had them in the first place, and we just took advantage of them or just didn't even have them in your mind. But, all the times you were fantasizing over some other no good guy, the right guy was right there waiting for you to choose him. So he finally got tired of waiting so he chose another and you know she is not even close to what you were to him.
