When I give my resume to people and get nervous and say stupid things that ensure that they will never hire me. /facepalm.
Boss dude: "What positions are you interested in?"
Me: "I'll do anything really, it doesn't matter." (This is an engineering place, I can't do engineering or machinery jobs so I'd be restricted to administrative, janitorial, or assembly work. So by 'anything' it's understood by both me and boss dude that I mean one of those three. Boss dude and I have known each other for a year or two, this is not a first meeting by any means.)
Boss dude: "Sure it matters!"
Me: "Well, um, I'd really just like to have any job that will help me pay off my student loans so I can go back to school."
What boss dude said: "We'll see. We'll talk it over in the next few days."
What boss dude probably meant: "Smelly child, you can't come look for a job if you don't know what you want, and I am not going to go through the bother of hiring and training someone when they've admitted that they want to leave me someday to go back to school."
What I said: "Thank you, <Boss dude's name>. I'll talk to you soon."
What I meant: "Thank you, <Boss dude's name>. Now excuse me while I go bang my head into the wall for being a flubber-mouthed moron."
