Hi gpelle2,
I’ve been thinking about this since i read your post yesterday. I’m so glad you’ve come so far.

My reply would be, “I had a bad cut/injury/wound a year ago. I’m so pleased/happy/lucky how well it’s healed up.” Stop there. Then I would change the subject. “Do you know where to find…. What do you think about…That’s a lovely outfit…How about that football team….etc. Have a transition in mind and practice it ahead of time especially if you’re like me and don’t ad lib well. 🙂

People are people…and some people are nosy and will press. Reply, “It was a difficult/unpleasant/unhappy time/event/accident and I really don’t like to talk about it, but thank you for your concern. I appreciate it.” Smile and use another conversational transition.

If they try again, you have my permission to be blunt or rude. “I’m really not comfortable discussing it with you. It’s something i only share with close friends/family/god…” And at that point I would walk away because they’re clearly not someone I would want to be friends with.

You can be vague, but truthful. But honestly it’s nobody’s business but yours.
