For a while, I thought this suspicion was something to work on and get rid of, but upon further reflection, I realized that I think I will always be suspicious of garbage disposals, the same way I would be suspicious if they started building wood chippers, chainsaws, or rabid pit bulls into sinks.
Yes, it might be a quick way to get rid of food waste, but that doesn't mean that I won't get a little nervous each time I turn it on and it devours food scraps while making that hideous noise, or worry that it will mysteriously activate and eat my hand when I have to reach into the blackness and gingerly fish around for a rogue spoon that has disappeared into its maw.
