I am tired. My arms are sore from doing too many liquid-liquid extractions (my current record is 9 extractions a day). My feet are sore from standing while I was extracting. I am tired from writing an article that my adviser only informed me to write in the beginning of the month… And the deadline is the end of the month.
I went to school the whole long weekend, 3 days with 10+ hours in the lab. And this was taken when it was raining on Saturday.
