My poor mother had this when Dad retired. He 'helpfully' would accompany her when she was doing the weekly shop. He would question every single thing she bought with 'why do we need that? We never use that'. She had been doing this shop unhindered for about 40 years and found it infuriating.It's true though. If you're used to having the place to yourself for most of the day, having a cranky, retired husband getting underfoot suddenly, disrupting the usual flow of your day, would be so bleeping enraging.
