My family knows all about my cycling and is supportive. I suspect that some don't entirely
understand the cycling, especially the really long distances, but they're supportive.
More "challenging" was dealing with work (office) situations. I've done some serious damage to my left knee on several occasions, and it is pretty badly scarred. Fortunately the scars are fading a bit now, but there were several years where I didn't feel comfortable wearing above-the-knee skirts in office situations because that knee looked that bad.
