Well, my wife would tell you that I think I'm the only one who knows how to load a dishwasher, which is why I come behind her or others and re-load it, or at best fight the urge.
I re-load the dishwasher because I'm apparently the only person in the who actually knows how to load a dishwasher.
I also seem to be the only one who knows how to take the recycling out when the bin is overflowing.
