A naughty schoolgirl knows there are two times that should cause her to worry the most. The first is when her father gets home from work.
The second is when her Mom comes into her room at bedtime.
(A side-note -- For years I've looked at the first drawing and asked myself, "A spanking with nineteen what?" Was it actually a reference to her age? Should it have been "A Spanking AT nineteen"? Or was it referring to the number of swats she was going to get? Nineteen smacks seems like a pretty light sentence, though. I guess it's just one of those things I'll never figure out....)
