I was a few weeks away from being 21. I made a big mistake when I moved out for the first time - I figured 800 miles would be enough distance but it wasn't and that's why we now live 4000 miles away on a tropic Island in Canada. Cheers!
I was 18 when I moved into the college dorms. For the next four years I visited my parents but didn't "live" there. Although I came back while awaiting news from grad school and I came back last year during the pandemic.
