So, here is a very badly drawn comic, featuring Kitty and Leslie.
Now with an added guide for those who can't read my tiny handwriting! Ahem.
Kitty: ...how many packs of cigarettes are you going through a day?
K: You heard me.
L: I don't want to tell you because you'll make that face.
K: What face? This is my face. It does not leave me at night when I sleep.
K: ...that I know of.
L: You get this face when I answer questions I know I shouldn't. "Leslie, did you set that trash can on fire?" "Leslie, where is Mrs. Watson's dog?" "Leslie, did you eat that hobo?"
L: I'm down to three.
L: See, that's the face. The boy makes that face, too. It's like you share a facial expression repository.
I just like the way Leslie holds up three fingers.
