I don't know where you live dood, but folk are constantly moving in and out where I live...

Why do you think it means something sinister in this case?

How often do people normally live somewhere? What's the norm for that town?

If you don't actually know those things then you have nothing to compare it to, and no story.

How often have you moved? How many times did you move while you were in school?

I have friends who moved 3 times in one year, and others that never moved at all.
