Panel 1: We start things off with Michael trimming the hedges. Since it's Mother's Day, we've been programmed to expect his and Elizabeth's standing around slack-jawed because Elly will not pay them to do what they owe their parents.
Panel 2: We zoom out to see that Liz is standing behind him putting the clippings so they can be composted.
Panel 3: Next, we have them team up to do the mowing. As he mows the grass, she follows along with a big basket so as to put the clippings in to take to the compost pile.
Panel 4: Liz rakes the clippings together.
Panel 5: Having gathered them together in a basket, she dumps them onto the compost heap as Mike and Connie look on.
Panel 6: Connie praises them for the nice job they're doing cleaning up.
