Common Sense isn’t so common anymore.
It's so rare it should be considered a super power. (Stolen from my teenage daughter).
With regard to the dryers - I think mine was on a list of brands that Lowes Hardware Store had problems installing properly and had lint buildups and would catch fire. (A kinked hose or something). Mine seems to be fine, but I have been meaning to look into it more.
I do only run the dryer now during the day when I'm around. I figure then at least I might have a chance to hear the smoke alarm on the ceiling 2-feet above the drier and unplug it and hit it with an extinguisher. Or die drying - I mean trying.
