Sometimes you would rather be alone on the hiking trail. But you're not. That's why you have to come to terms with the others and no one really has anything against a smile and a smile back.
In Graubünden, biking is generally allowed on hiking trails, unless an official ban expressly prohibits it. Of course, it is also clear that hikers can count on the special consideration of bikers and enjoy the right of way in any case.
