It's so ironic. I look at Sheldon who grew up in a loving home with an adoring mother and he turned out like a robot. I on the other hand had a mom who treated everything as an experiment including raising children since I was 3 and I grew up to be a loving warm and caring man. Oh I'm not saying I'm perfect. Believe me I'm not anywhere near perfect. I've made mistakes. I've done things I regret but I think it stems from my lack of self esteem. I need to know with Penny for example that her love is not conditional.
It's so hard to be an after thought. But I have something better. I have my Penny. I know Penny loves me even when I'm less then perfect. I remember one time she was mad at me and I said, "I can change. What she said next brought tears to my eyes.
"Don't," she said, "I love you the way you are"
