I'm not gonna even try to hide the fact that I'm kind of a goody two-shoes. I blame my rebelish childhood for being such a straight-line woman.
I don't smoke marijuana like half the people I'm related to. This also clearly implies that I don't do any drugs and I never will. When I say I'm going to be somewhere, I commit. If there's a due date on something, I turn it in early. I have manners and know when to mind them. Etc... etc...
When people are literally 100% opposite of that, it makes me feel extremely uncomfortable. For example, I am related (by law) to someone who bullies people constantly, smokes weed, and doesn't take responsibility for anything. Yuck. Not exactly my cup of tea.
I'm not saying you have to be the girl next door to be my friend. But you are associated by what company you keep. So why would I want to be known for something that I'm not? Call it whatever you want, I call it trying to be the best person that I can be.
