Just because you can't ski doesn't mean that skiing sucks. On the contrary, you suck, for being so jealous of people enjoying a sport you can't. You must feel excluded. Kinda like the Mounties who plod down a glacier slog when a skier comes zipping by, hooting with glee. Sour grapes, perhaps? Sad....
But wait. I know that you do know how to ski. Maybe you just can't stand not being elite in a discipline? That's also too bad, the rapid discovery and progress when learning a new sport is wonderful.
While you're getting frustrated flogging yourself on 10 feet of rock, I'll be having fun in the mountains, floating through the fresh. Don't be jealous.
