Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
A broken heart in real life isn't half as dreadful as it is in books. It's a good deal like a bad tooth, though you won't think THAT a very romantic simile. It takes spells of aching and gives you a sleepless night now and then, but between times it lets you enjoy life and dreams and echoes and peanut candy as if there were nothing the matter with it.
