I can't see your profile for some reason; when I try to view it I get an error screen and the message "This member limits who may view their full profile." If you're still a middie, you're not a SNFO. You'll get your designator when you get your commission. Until then, you're a prospective SNFO. And you can tell your XO that I said that.
Prospective Student NFO? What is a guy who wants to be an NFO but hasn't gotten an ROTC scholarship yet? Future Prospective Student NFO (FPSNFO)? Whatever.
Mid1510: this is what Obama would call a "teachable moment." As an aviator in training, there will be a myriad of special "not until you have earned it" rules that you can choose to be worried about or not. "Don't wear your leather jacket, you might jinx it." "Don't wear brown boots until you get to the fleet" ... gee, what do you do if that is what you were issued...? "Don't double click the mic" (actually, thats an important one). You may or may not get lots of shit from people for doing something or wearing something you haven't "earned". Some of these traditions are more important than others. Its hard to tell which are which, so you will take your lumps along the way and realize after the fact what was important and what wasn't. Thats part of being in this club and being a big boy. Don't be disrespectful or arrogant, but don't be a pussy either.
I consider SNA and SNFO kind of made up titles anyway. Now if you misrepresented yourself as a winged NFO, or something that is actually more official, that would be a different story.
