Mrs. B: Who's coughing?

Matteo: Me.

Mrs. B: You sound awful. Do you want to go home?

Matteo: No.

Mrs. B: You sound pretty sick.

Matteo: Yeah, I really am, but I don't want to go home.

Mrs. B: Well, try not to breathe on anyone.

(Girl sitting next to Matteo slowly, surreptitiously pulls her shirt collar up over her nose. I see this and start laughing.)

Girl: Well! I don't want to get sick. I love school!
