I'm not cool

I am not what people consider to be "cool material". I have actually never been nor pretended to be cool. I believe this "being cool" stuff begins actually in high school and back then I never had a boyfriend, nor any guy was interested in me romantically. I was never the girl other girls or guys invited to their parties and I was always one of the last ones other kids picked to be in their teams, in gym class. My gym teacher somehow had a preference for pretty skinny girls and was extremely condescending with me.  While other kids were pretending to be adults, smoking, wearing make-up and making out I was buying barbies and making dollhouses (yes I was 15) because I knew there would be a time when I would actually be an adult, and then I wouldn't be able to pretend being a kid.
