(Strip Number 1214, Original Publication Date, 26 October 1987)
Panel 1: We see Elly calling Mike's name and not getting an answer.
Panel 2: She finds him sitting in his room and listening to terrible, terrible headache music on his Walkman.
Panel 3: She then yanks his headset off and tells him that he can't possibly hear her.
Panel 4: The rather blindingly obvious dawns on her when she then asks if that's the general idea.
Summary: This, as howtheduck is probably sure to show us, the first in a series of strips that have a child use a headset to block out the angry whining about how cruel a child is being to his or her poor mother. It's also a lead-in to a reminder that Elly is and always will be totally unaware that her children want very much to know if she loves them at all.
