Weird first post, I know, but I've moved to Germany recently (3 weeks ago) and am living happily in Freiburg. The only thing aside from the bureaucracy that's really been bothering me, though, is how to say bye. I never used to say "tschüss" when I visited but it's gotten too hard to get around without. I've been told "ciao" is a little flirty, which, in an office full of women (about 85-90%) might be a bit problematic. "Servus" is more of a greeting (though I do love it), "auf weidersehen" is too formal, "ade" is too definitive, and while everyone would understand "bye", that's, well, English.
Have I just disqualified every way of saying "bye!" to Germans? I don't think that "bis bald" and "bis später" count, unfortunately, since everyone always says "tschüss!" right afterwards. Though I would be fine with those.
And, of course, if you want to jump all over me for such a ridiculous first post, please feel free -- I won't mind. :-)
