Circumstantiality

Refers to a thought disorder wherein thinking takes a roundabout manner to get to an answer. Differentiable from tangentiality by the speaker eventually getting back to the point. For example: "My mother's job? She used to sit around the house doing nothing but drinking, she'd just sit there and stew, making noises, chugging her drinks. She threw my dad out of the house. I'll never forget that, the way she did it. Anyways, my mom was a waitress."
