Left to right
Three silent penultimate panels today. Well, two are really time-passing panels and one is a vacation reprint, but I'm counting them all today.

Because we read from left to right it can sometimes be difficult for a cartoonist to get the character blocked on the right side of the scene to say something first. There are a few solutions.
Put the word balloon above the other character's.
Swing the camera around between panels to show the characters from the rear.
Or simply have them magically trade places.
Only of these solutions is lazy.
