Being utterly messed up from a head cold and having to deal with kids being unruly at Smartcape.
Academic librarians never have to deal with this. But then we don't have to deal with screaming lecturers and professors who have entitlement issues, as in:"I don't care if it's the only copy in the building, I'm a professor, I have tenure, I'm ENTITLED to it. Bow down and kneel before my doctorate."
At least we get paid better now.....
