Good luck, honestly its a few days of torture (riding exceptionally slowly beside your gaper friend as they pizza in your tracks while your friends ride by doing their cool shit haha). But my bestie has never skied before last year and i brought her to our place for a weekend, taught her all i could, and this year she might still be slow but shes doing (mind you easier ones) blacks, a bit of trees and in general moving a lot faster.
Its sick to see someone grow into a good skier if you were the first one to teach them. Show them how sicccck skiing is and hopefully you start something with them - my friend loves it now. Better gear and maybe even her own skis and shes doing great. Have fun!
