Name That Title Please

[glenbo]

I'm looking for the title to an O. Henry short story that involves a married couple. They go about their day either being helpful or nasty to people they encounter then switch roles the next day. Thanks in advance to anyone who can help me.

you're actually thinking about "one ordinary day, with peanuts" by shirley jackson.
