I subbed for a senior English teacher today.
The school was having some tech issues this morning, and could not get online to access emails. The teacher I was subbing for had emailed in her lesson plans, with the idea that the office would print them off to me. Instead, the office had to call her and ask her to email them to me, where I could then read them on my phone. It really wasn't a big deal, but it did mean that I had to be looking at my phone off and on all day.
I'm sure at some point someone important walked by and saw me, then put me on the school's blacklist.
