Could you live in the same small town your entire life?

Specifically, towns under let’s say, a couple hundred thousand people.

The town I live in has about 100,000 people up from 83,000 ten years ago and is the largest in about a 2 hour radius. Most of the other towns around here have between a few hundred and maybe 75,000 people. I went to high school for two years in a town of about 4,000 and I know people who not only grew up there, but are now raising their own families there. They’ve never left. The town I graduated high school from has 25,000 people, and the same thing applies. What’s even more odd for that particular town is that many of my school acquaintances actually went away to nice universities, got bachelor’s and master’s degrees… then went back. To stay. This baffles me. Maybe I’m a roamer. Maybe I just want to try new things, meet new people. I’d like to hear everyone’s opinions on this.
