One of those days

I've been on campus for about twelve hours straight today. The nose-rest on my glasses broke during my second class. I mixed the wrong buffer because when the protocol called for EDTA I used the thing labeled as EDTA instead of the thing labeled as disodium EDTA and so ended up with the iron-sodium salt instead of the disodium salt and have to remake EVERYTHING tomorrow. The pH meter was broken so I can't go any further until we get a new meter in and I had to wait for the professor for about an hour because she forgot I was there.

I was told there'd be days like these.
