I get the feeling she had this conversation with her brother/parents/somebody. She wants to enlist so they'll get off her back about not going back to school; they tried to convince her to go to college and become an officer. She came on here looking for people to tell her enlisting is a great way to become an officer without any of that totally stupid, boring pointless college stuff. When she didn't get that, she made that W sign with her fingers the kids are always doing nowadays and stomped off.
Otherwise, I can't fathom a reason for all her posts to boil down to stuffing her fingers in her ears and going LALALALACAN'THEARYOULALALA!
