Yes, I know that you are right, because I have been much on my own from the age of 17 on when I was in the army, and after it I had a job 50 kilometers away from home.
So I learned quite early to live on my own, but it's not easy to let my son go, although it gets easier each day, because most of the time he is sleeping in his girlfriends apartment anyway 😉
Cheers and !BEER
