The label you choose for the individuals who ski with you can dictate the way you speak to them and possibly the way you treat them. This cooperative relationship may foster your creativity and their acceptance of your efforts. If your students are your guests, you should be polite, kind, patient, and serving. You should also attempt to meet their needs. Any effort to center lessons on guests must include some careful attention to how you say what you say.
Commands are also inappropriate for guests.
For example, you probably would not order a guest to clean your house. Similarly in ski instruction, commands are not as effective as directions framed in a positive manner. Maybe you should do the same. However, many instructors regularly critique and compare the skiing techniques of their students during lessons. Application is a useful alternative to comparison.
