My great Aunt was a librarian at a university, where my great uncle was studying to be a teacher. He's very shy and thought she was pretty so he would go in and check out books as an excuse to talk to her. After about two months he realised he had a huge stock of books that were overdue that she had been too polite to remind him about, and he sheepishly had to carry them all. She told him she would get rid of all his fines, if he took her to dinner..............................................
Three kids and 65 years of marriage later, they're still the best couple.
