I might be leaning too heavily on the “ooh this romantic couple is being passive aggressive” stuff, but I still really like this one.  I like to think Joyce is speedily crafting the pie chart off-camera during panel two.  Either that or she just keeps a pie chart that says “PARK BENCH” with her at all times.  Maybe Walky does this a lot.  But pie charts are funny, dammit.  They’re almost Oversized Comedy Props.
