I've come to realize that we see what we want to see. Deep down, we know things and play games with ourselves, some thinking that if we wish it away, it will disappear. Kind of like, if no one says it out loud then it really doesn't exist. It breaks my heart to see a woman do that to herself. It's really a drag when everybody "knows" except you.
Another thing that has always amazed me is how important it seems to be to people be the first person to tell something. I wish more people would adopt the "just stay out of it" line of thinking. I really prefer to let the person bring it up when their time is right.
