Get used to you instructor yelling snoooooooooooww plowwwwwwwwwwwwww as you slide down the nursery slopes, for that is all you will hear for the next 6 days! You're never quite sure if it's you they're shouting at as they all sound the same.
If you're a lady, and are desperately caught short on the mountain, take your skis off before crouching down in the bushes (yes I've seen it happen ... the backwards movement, the surprised look as you realise you're moving and mooning the whole resort)
if you see a person on the ground covered in snow with skis twisted in all directions, try and swerve round them rather then skiing over and off them - they are not (usually) a human jump - unless of course they're a boarder
