This one is inspired by how I think I've developed, how changing homes a lot as a kid and constantly being exposed into new social groups made me sort of nasty as a defense mechanism and how this has carried over into my adulthood.
I'm not entirely sure if I am a bad person, or nasty or maybe even good, but I think I can be harsh and perhaps self-righteous, and loving with all your heart can't excuse a venomous tongue.
