Moved in with parents and don't know how to respond to nosy neighbor?

I lost my job some time back and lived on my savings for a while until they ran out. Now I’m living with my parents until I figure something out. But a real annoyance is our next door neighbor. When I moved in, he came out and asked me how long I am going to stay. I said “maybe a month”. It looked like it stumped him when I didn’t follow up with any information about my situation. But he approached me yesterday (two months later) and I kind of dashed past him to avoid dealing with his questions.

I don’t want to be rude to him because I don’t want to mess up my parents’ cordial relationship with him.

But I also don’t know how to protect my privacy since I have no desire for everyone in this small neighborhood to know all of my business.

Next time he sees me I’m expecting him to ask questions like:

- You’re here longer than I expected . . . ?
– What line of work are you in?
– So, are you working now?
