Because sometimes they would have been the worst things for us.
Tonight, I lied. But it was to spare your feelings. And you probably won't remember anyway. But I did lie. And I'm not a liar so I feel guilty about it. I want to be honest with you and somehow not hurt your feelings at the same time. But you aren't honest with me and you hurt my feelings pretty frequently too. I'll never get what I wanted from you, but I can only control my own actions. So, I'm sorry that I lied. But it was the only way to avoid telling you things I will never never tell you.
