Lepers ?, used to say I've got leprosy, to keep do gooding, cheerful c**ts away from me years ago. I aint the most sociable of people at the best of times, but f****n HATE bubbly, joyful types asking me if I'm ok, or 'how you feeling' etc lol.
Not quite as bad nowadays, but still not a 'bundle of joy' to be around ?
