Rain, sex and drinking..
For me, around 1991 I was working in a hotel in a tiny blip of a village in East Anglia where two-thirds of the homes were second bless-tihs-hosues owned by affluent Londoners as weekend retreats... after a day in the kitchen, the only recreations open to staff were sex and drinking, both of which pale after a while.
Luckily, I discovered one of the tourist tat shops had a bookshelf, and while 90% was instantly forgettable, there was a copy of something called Wyrd Sisters by Tery Pratchett available.. that was it. Bought it, read it, got hooked, begged bookseller man to order all five previous books for me.
And i've never looked back...
