The person who lives next door to my house asked me where I work? How to say? I don't want to tell those people or let them know where I work

The person who lives next door to you asks you where you work.

It may be out of concern,

or it may be curiosity,

If you don’t want to tell those people,

you can just mention it anywhere,

They may not know the company you are talking about,

You can play it by ear,

I hope my answer can help you.
