A simple gag today, a gentle play on the difference in age (and marital status) between Suzi and Debbie. The two-step nature of the gag allows Roberts to insert a wealth of detail in the left hand image. Note that, even in their winter coats, Suzi and Debbie are distinguished by the same black/white contrast. This also works to distract attention away from the slouching guy at panel left, giving an admiring glance to Suzi: her black coat lands the eye in mid-image, progressing naturally rightwards from there and leaving him to smirk almost unnoticed. Beautiful staging.
