Work anniversary

Yesterday I had my four year work anniversary. Four years! Of course all the cliches come with working somewhere for any length of time. 'Time flies, huh?' 'Bet you lost track of time.' Etc. Etc. Etc. I never really thought about it. I don't think you should really count your anniversary at work until you get past five years. Not to say people job hop once they get out of college or high school, just that anything under five years doesn't seem to warrant a bench mark.
