That’s a possibility.
In the context of this comic, and this arc, I doubt that Andy’s mom would say anything of the kind. I suspect there is more to be revealed down the line. It is interesting to see in the comments that some people see what it is that is driving Andy crazy about her mother and others that believe it’s all Andy’s issues. That may have something to do with readers’ varying experiences with family dynamics.
The problem is her mother is being very passive aggressive and it’s pushing all of Andy’s buttons. The fact that it’s subtle passive aggression (that is probably lost on the rest of the family) doesn’t help matters.
Andy’s raising three children, cooking for her family and has just been saddled with an unexpected house guest for two weeks. I’m not surprised she might be backed up on her work.
There’s a joke here somewhere about not being the brightest bulb on the tree…
Roger’s certainly a menace when he barbecues. Have the kids ever cooked?
Ummmm. Pickled herring!
Didn’t he find her eventually?
No answering machine, I assume.
What she’s doing is subtle but undermining of her daughter.
