I have to teach my friend to snowboard what should I tell her?

Lessons! People either pick it up very quick, or need to actually be taught by someone who is paid to spend multiple hours showing them technique. Have here watch youtube on snowboarding a few hours before you try and show her. I tried teaching my girlfriend! After hours of no results besides her falling on her instead of her face lol, I left the slope with her to relax in the hot tube...No boarding for me that day, and now she hates snow now! So i should have just bought her some lessons.
