Something always goes wrong, however impeccable your planning. If something goes awry, don't panic and keep smiling!
- Surprise guests: all of a sudden you could be 5-10% up on your estimation! Stay calm: the more the merrier. If you don't like some of them, don't stress about it - you don't have to spend much time with them.
- If someone gets absolutely wasted: stop them drinking any more alcohol, give them plenty of water and let them have a sleep or get them a taxi.
- Culinary disasters/accidents: don't panic! In the worst case scenario, you can always order some pizzas in!
- If there's not much atmosphere, again don't panic! If you look like you're having fun, everyone else will do the same, so smile and enjoy - laughter is contagious!
