An important conversation

We were having this conversation yesterday, and I thought it might be goat-relevant, paraphrased:

D: So I was waiting for the Broad Street Line this morning and there was this fat woman spreading cream cheese on a bagel with her thumb. It was the grossest thing I've seen in some time. I kind of wanted to throw up, or punch her.
E: That's not that bad.
T: Was she just fat, or morbidly obese? This is an important detail.
D: Morbidly obese, why not?
T: Yeah that's awful. A disgusting human being in body and spirit.
E: Give me a break! It's not gross, it's her thumb!
T: Have you been in a Philly subway station? Eating anything in there is a terrible idea. So many homeless men pee in there that the air is permeated with urine molecules. Touching subway tokens and then eating? Horrible.
E: But it was her thumb! Are you saying that eating a bagel without the cream cheese would also be gross?
T: Well, it depends on what kind of bagel. The viscosity of the cream cheese certainly adds a level of disgust.
E: The cream cheese makes the bagel! And it was her thumb!
D: It was a plain bagel.
T: OK, the cream cheese is necessary because it was a plain bagel.
E: She just wanted a tasty breakfast, and didn't have a knife.
T: Wait, she had a tub of cream cheese? and was scooping it out and smearing it with her thumb? I now have a full mental picture, and it is awful.
E: Give me a break. Who cares? If she wants to take a chance at contracting some Philly subway germs, it's her risk. Who are you to judge?
T: If someone makes the decision that they need to spread cream cheese on a bagel with their thumb in one of the most disgusting places in America, I will judge them, and declare them gross. Unilaterally.
