re: Proper etiquette for leaving a company?

I was a bit nervous when quitting my first full time job after college as my boss was a good drinking buddy after work. I asked him if we could talk one afternoon after work and explained that I had an offer to return home for a more long term career. He was happy for me and wished me the best of luck. It's really not a big deal, you're an employee straight out of college that has been there for 4 months. If you already are getting offers then it's better for them in the long run anyways
