When someone will put up with a light bulb being out for days or weeks because it's a man's job to replace light bulbs or something.
When the lightbulb goes out and the man won't change it because it's the woman's job even though she a lot shorter and has to drag out a ladder to do it and the man could reach it easily.
Height is not an issue in a world with ladders, step stools and chairs. The ability to change a light bulb is source material for innumerable jokes for a reason, because there is nothing in the world that could possibly be easier. Since this is a thread about pet peeves I chose this one because there is flat out no reason why
anyone regardless of their sex (or age past, say, six) should not be able to replace one.
Which brings to mind another word mis-usage issue...
Using gender instead of sex in reference to a person.
Gender is a property of words, not people. People may be divided by sex, male or female or liberal Democrat. Words can have gender, masculine or feminine or neuter.
