 There are lots of questions that seem like they would produce a simple yes or no answer, but in fact they don't.

I think I annoyed my brother a little bit by answering "yes" to "have you got a barometer?" and then, after quite a long conversation answering "no" to "have you got a serviceable barometer". However I stand by my first answer. I kept my late father's barometer for sentimental and historical reasons. While the needle does move a little bit, it's unreliable and wildly out of calibration.

If the answer to "have you still got dad's barometer" is "yes" then the answer to "have you got a barometer?" must also be "yes"
