TFLY,
Yeppers, a graduation and everything! You work hard for three weeks learning drill... you work hard at figuring out what you want to do... you work hard at maintaining your uniform! And you work hard at your discipline in all aspects! Why the heck wouldn't you be deserving of a parade

It's part of the job, baby!
It's also a proud day for the staff too, who (trust me!) deals with a lot to get you guys into shape.
The policy is no contact with outside peoples (like, you can call family almost every night... unless you have inspections to get ready for and you can only call after all the work is done)... but, there's no fraternizing (males or females!) of other people from other courses. Keep in mind that most of the participants are around the ages of 17-21... so, this is more to protect them than to protect you

But, you still need to abide by the rules or... it's a one-way ticket home!
But, if you make arrangements ahead of time for the last night, you may be able to arrange to go out. But, they have a strict no drugs/no alcohol policy (and I believe that includes the last night... because of legal reasons, you are still their responsibility!)
