Panel 1: For some reason, we find Liz walking down the street wearing a pair of Elly's shoes. Said reason is probably so that evil snarker troll fungus people might be irritated by having to watch Elly overreact to a horrid pun.
Panel 2: As she starts to change direction, one particular basement dweller asks himself if she's smiling at the unsound effects she's stirring up.
Panel 3: She starts to head back into the house.
Panel 4: When she tells a horrified Elly that she just walked a mile in her shoes, we are left to gaze in awe at the display of skewed priorities.
Summary: This is because while Elly will always remember this incident and hold it against her child forever, the business of throwing a teddy bear at a bus driver in cross town traffic will be forgotten.
