Linda McLean 
Any Given Day (NHB Modern Plays) [EPUB ebook] 

A sharply perceptive, darkly funny riff on urban isolation by one of Scotland’s leading playwrights.
This is a big day for Sadie and Bill; their favourite person is coming to visit. They’ve gone to great lengths to prepare for the occasion. It’s an even bigger day for Jackie; and not one she’d anticipated. Should she make the most of it? She doesn’t know if she can any more; too many people depend on her.
Any Given Day explores our fear of the unknown, and our guilt and responsibility towards ourselves and others.
'as bold, unnerving and fraught as anything Mc Lean has written' – Guardian
'an excellent play which truly does horrify on so many levels' – Independent
