@MartinPerry1 That’s not a recommendation. It’s an arbitrary rule of thumb for which dating a younger person becomes creepy (male or female). E.g., by that metric, a 50 year old shouldn’t date anyone under 32.
I think the strip isn’t as focused on SUVs in general, as it is on the fact that the driver is Stephan Pastis. Frazz and Pearls have had an occasional, subtle back-and-forth for at least a couple of years, now (as have other strips and Pearls).
Hot air balloons launch at dawn, so this would be sunrise.
