For us, it's an everyday question: why don't we know this? More often than not it's a little embarrassing the levels of our ignorance. Usually, we try and cover it up with a blank smile and few enthusiastic nods, but below the surface we're praying a question is sent our way. Well no more friends! We're determined to learn what we should have already known before we started adulting - and you're all welcome along for the journey.
