I've had a crush on you since my early teenagers. Would you please go out on a date with me? I live in Oslo. (My apology to your girl if you're taken, but I think she'll understand me.)

I am flattered, Lise. But as you anticipated I am taken (as you might call it – hehe). If you should however meet me in Oslo or somewhere else, introduce yourself and who knows, maybe I am just waiting for someone to kill time with.
