No John Stanley this time, but a timely message from one of those Golden Age comics PSAs that gives you advice so obvious, you wonder if the real message is "our readers are cavemen." (One clue: The "advice" is given to humans from a dog.) This is from a coverless humor comic from the 40s from National Periodicals. (One of the funny animal titles, don't know which one.)
You have to feel for Terry. Maybe he could accidentally "go missing" at a rest stop and find a family that remembered to load film in their camera (and packed some kibble).
I also feel a little bit sorry for "Dad." He makes all the mistakes, but I don't see anybody in his family helping. Give your brain-damaged father/spouse some help, gang!
