I prefer not to say that I've LOST something. Rather, I'd prefer to think that I'm just hiding things from myself; making a game of it.
Perhaps, in other aspects of life, we could be more playful, like, "I'm not writing a report for my boss, I'm finding new words for Scrabble." or "This isn't an awkward first date, it's 20 Questions."
Life could be a lot more fun, don't you think?
