Looking Over Last Year's Application

So, I printed my application to look at what I can improve. I read my answers to short explanation questions. I was horrified at my bad manners. I didn't mean to, but I sounded like a smart-ass. There was too much me in my answers. I have a severe food allergy, so I had to talk about what it was and since when and blah-blah-blah; my answers sounded flip and unprofessional. This was incredibly stupid of me. I should have been straightforward and simple. This is an easy fix that I can blow through to be better next time... You may not sound rude in person saying in the words you use, but on paper there is no way for the reader to hear you actually saying it. So, yeah, don't be flip or rude by accident.
