I have so many animate objects that it’s hard to be too angry at the inanimate ... although I’m getting pretty enraged with the coffee maker, which is showing a “Clean Me” light even after I cleaned it.
I blame engineers.
DP should be already aware that you have a simmering rage against incompetent engineers. That is undoubtedly why he treads cautiously around you.
Since I only make coffee two to three times a week, I run vinegar through the machine once a month, just in case there is some mold growing in the water that’s left in the reservoir. And since it’s a Keurig, it only holds water, not coffee. One of the things I like about it. :o]
