history: When I joined the army I was really nervous.  I joined the Army when I was 18 because I didn't know what else to do. I was so nervous! I am sure you were.  Was boot camp really hard Physically it wasn't too difficult. It was mentally difficult though. 
current: I could never do something like that.  Thank you for your service
next: I am glad I did it. I wasn't glad at the time though.
