I regret not being kinder to my siblings. Especially my sister. I said and did some very cruel things to my little sister. Today, she has horrible self esteem issues now and I can’t help but wonder how much of that was me. I feel especially guilty because I was dad’s favorite, our brother was mom’s favorite, and she was no one’s favorite. There were occasions when mom would tell me to be nice and that “your sister will be a part of your life long after your friends have moved on.” I regret that I never listened. I worry that I might be the worst thing that ever happened to her. This is especially bitter because when I went through a health scare, she was the only one there for me.
