Technology is amazing

I didn't have a PowerPoint needed for Life Science - which I'm teaching for the first time in many years. My dear friend and colleague left at noon. She took her computer along to check for it while waiting at an appointment. As class was starting, I got a text from her--thirty miles away. "Found it! Emailing it to you now." I checked my email, it was there, I downloaded it, and taught from it. Technology is amazing.
