Funnily enough my mum and her sisters refer to the cupboard under the stairs in the house they grew up in as "The glory-hole".
Akin to an Aladin's cave, a trove of treasure.
That was an awkward conversation explaining what it means these days and it may not be a good idea to refer to it as such in company.
Not a conversation I thought I'd ever be having with my wee maw.
