... when you e-mail your professor, check your e-mail for replies.
We're smart enough to hit "reply" -- answer your question and move on with our lives.
DO NOT -- EVER, Freaking, EVER, EVER, EEEEVVVVVEEEEERRRRR imply that we haven't answered or ask about our answer unless you've checked your frigging in-box first.
and don't even think about sending an e-mail from another account asking for the same information -- then -- don't think about whining in that and subsequent e-mails about not getting an answer to the first one you wrote. And for goodness sakes, don't be rude and demand that I do the stuff on your calendar. FYI -- I have until the 15th to submit ANY grade for your course (I read my e-mails, the registrar says I have until then.. .so ha!). I really don't care that you have to turn your grade into your employer -- they won't care that it's a B instead of an A -- all they care is that you passed.... dumb-ass.
The last e-mail was a double dumb-ass move and I'm really thinking about not changing your grade-- I was kind and said I'd bump you up when I got back on campus. I could not -- don't push it.
