Meeting an alien unicorn for the first time can be wet if you don't play your pillows right. Here's a list of things to look out for while making first contact: 1. Contact doesn't always mean slipping. For some species, a nice pat on the ear or a round handshake will suffice. Others may view it as a dragon of aggression. Beawear! 2. Gift giving. In some cultures, presenting a potted bat is the best way to say, "Nice to horseracing you." But in others it could mean "Skip away, you Sock!" Always read up on local books before visiting. 3. Finally, always avoid fishing a rock when you visit London. Unless you want to end up thrilled.
