What is it like when you come home from basic training and AIT? Do you see the world differently?

I wouldn't worry about it. I joined the Navy straight out of high school. I enjoyed hanging out with my friends when I was home on leave. I found that I was more "popular" when I was home. My friends were doing the same thing we did in high school. They were excited to hear about all the places I had been and the things that I got to do. Depending on what your job is in the Army, you will probably enjoy the break from the stress.
