But I studied other people and read signs, and soon figured it out. And now that I can
Stop in the lift line to put on your snowboard or skis/wait for your friends/ask the lifty random questions. Look, I'm not really in a hurry, but those Super Seniors behind me need to get their vertical, darn it! And if it's below zero, everyone behind you is freezing.
Stop right below the off ramp and have a conversation. Some of us, ahem, aren't as good at turning immediately after getting off the lift and need a little more room. Move to the side and chatter away.
Yell instructions from the lift. You may think you are being really helpful to beginners by screaming, "Bend your knees!" However, because of neck warmers, scarves, and distance, it's hard to tell whether you are saying "bend your knees" or "I'm your niece." Also, sudden yells from the lift are distracting and might cause said beginner to lose their concentration and fall.
Ask if the stranger behind you in line will take your overflow kid with them on the lift. Bonus points if you say the kid knows how to get off the lift when in fact, he does not, and sits there like a rock instead of standing up, causing you to lunge for him and pick him up, sending him safely down the ramp while you fall, looking like a fool in front of the lift attendant.
Stop in the middle of a run. Snowboarders do this more than skiers, but some skiers are guilty too. Make everybody, including lessons, swerve around you. Subtract a point if you stopped because you fell/lost a ski/lost your phone. Everybody understands.
Make fun of or get impatient with people. It's really brave to try and learn something new. You should admire those 70 year olds in ski lessons. And those adaptive skiers who slowed down the lift line the other day? I saw them going over the jumps in the terrain park. They're way better than you.
