ETA: And I'm right to do so.
Panel 1: Goggle-Eyed Elly stares horrified and asks what's wrong as her poor, clapped-out, overused electric can opener makes a grinding noise (rendered here as RRRCH-RACH-UNKA-RRCH-RRRRR!!!) instead of opening the can of whatever she's going to make for supper.
Panel 2: In response, she yells "OPEN THE [BOXCAR] CAN, YOU STUPID..."
Panel 3: She stares at us for a second as if she's aware that she has an audience.
Panel 4: Her next move is to make a panicky phone call to Annie to come quick because she's started to talk to her appliances and needs help.
Summary: As Poteet said, she's nuts but not for the reason she thinks she is. Talking to appliances is one thing but what she's about to do is quite another.
Postscript: Well, unless I miss my guess, we're going to see a note from Lynn announcing that the story is now strong enough to go into straight reprints. If so, we're about to have a lot less traffic on this site soon because, well, there'll be a lot less to comment on. I should think that there'd be days when there are less than ten comments.
