Since I've broken my ankle I've been on crutches and lately using a cane or visibly limping, which lets people in my environment know I'm injured. I'm young and generally wear work or athletic clothing, so this probably looks "off."
People, total strangers, frequently ask about my injury - "how did you do that" or "what happened?" This is without any prior discussion or contact.
Where are they coming from? Why are they asking?
