Things seen and heard

While re-writing and improving a section of my lab book, I found this exact sentence: "RT-PCR notes: First set of tubes should be a serial dilution to test the awesomeness of your primers"

While walking down the sidewalk this morning, I spotted a frail-looking undergrad struggling with four bags of groceries. Bitchily, I thought "Gimme a break, you don't eat food"

While re-assessing the need for my 14 departmental keys, I found a key I couldn't place. Clearly wasn't a university DO NOT COPY key so I tried it in my front door lock. Yup. I've lived in our house for two years and have never locked the front door once. Didn't even know I had the key!
