Neighbors

What's a normal relationship with your neighbors? Would you be bestfriends with someone just because they're your next door neighbor, have the same amount of kids and are the same age as you and your kids?

I feel like I'm being forced into this friendship, and I don't want to be rude. I like my space and my privacy, and to be honest, I'd rather our kids not socialize as much together 🙁

I'm not sure how to set boundaries without coming off as a mean person.

Edit: The kids are not very nice. Mine can aren't always the nicest either, but I definitely see negative tendencies on my kids after they hang out with them. My kids tell me all the time that they don't like the little boy because he's so mean. I just tell them it's ok they don't have to play with him if they don't want to, but this kid continuously name calls and blows raspberries and gets in their face.
