What do you say when a sweet kid asks about your white cane? Looking for a good “stock answer”

Hi! Longtime lurker, first-time poster.
I lost most of my vision pretty suddenly because of a brain tumor, and I’m still relatively new to navigating the world this way. I have about 85% visual field loss and use a white sight stick when I’m out.

I just want to say first that lurking here over the last several months has genuinely been such a comfort. I’ve learned an enormous amount from all of you, including answers to questions I hadn’t even figured out I needed to ask yet. More than anything, I think seeing people here talk so matter-of-factly about work, travel, relationships, parenting, hobbies, annoyances, adaptations, etc. has helped me understand how full life can still be with very limited vision. So thank you for that.

Anyway, I’ve been thinking about something much smaller and more practical lately: what do you say when a little kid sees your cane and asks something like, “What is she doing?” or “Why does she have that stick?”
I genuinely love kids, and I really don’t want them to feel like disability is scary, embarrassing, or something they’re not allowed to ask about. Usually the adult with them immediately looks mortified and starts trying to shush them or hurry them away, and I almost always want to signal, “No, it’s okay! They didn’t do anything wrong!”
My current stock answer is something like:
“My sight stick helps me see because my eyes don’t work as well as yours.”
Which sounds nice in theory, except approximately 100% of children then understandably go, “How can a stick help you see?” lol.
And I realize I could explain how I use it to find obstacles, stairs, curbs, etc., but I’m also not necessarily trying to turn a five-second interaction in Target into an educational seminar they and their parents are non-consensually forced to sit through. Mostly I want to give the kid an answer that feels complete enough that they understand what they’re looking at, while also giving the parent a graceful exit.
So I’m curious: have any of you landed on a really good boilerplate answer for kids? Something simple, friendly, accurate, and ideally not so intriguing that it immediately generates six follow-up questions?
I may also be taking on way too much responsibility for making sure every random child has a positive formative interaction with a disabled stranger lol. But because this is all still pretty new to me, I’d love to hear what those of you who have been doing this longer tend to say!
