Isn't a "detritus-chewing drain" a garbage disposal?

I'm happy that in today's strip, Al has returned to using the proper spelling of Migraina. That "y" in there totally threw me off.

As for the content...yeah. I admit it. I totally do this. (Did this. I don't have a dishwasher in my current apartment.) Because my mom does it, probably. Now, I don't have to get everything off the dishes, but I definitely scrape off a lot of it. It helps keep the dishwasher clean, I imagine, and it's really not that much effort. I can't really explain it. But rinsing doesn't mean cleaning, you know; it just means getting off the extra food remnants. But would she really call it "the machine"? That just rings false.

My question is, Did Migraina do the rinsing business with her old dishwasher as well? If she didn't, then yeah, this makes no sense. If she did do it before, well, it's habit.

Love the pageboy-haircutted son next to her.
