The smell of old ladies’ cardigans. Jigsaws with missing pieces. Well-worn paperbacks. Frankie Goes to Hollywood 12” singles. Faded wedding dresses. Clothes with a story to tell. Back issues of Reader’s Digest. Mournful, empty photo frames. Souvenir teapots from Whitby. People may not have realised they’ve missed them until now, but there’s an alarming lack of charity shops in Barcelona.
