The Assorted Mishaps of a Teacher in Training (Part 7)

We periodically use the classroom set of laptops to do research in class for projects or papers. On a semi-related note, our wireless network name has changed from Watertown-PS1 to Watertown_Public. However, the laptops still default to the PS1 network, so I instructed my students to switch to the new network name and wrote it for them on the board. However, in so doing, I neglected to add the L to public, thus advertising the Watertown Pubic network, which is an entirely different thing altogether (and, hopefully, a non-existent thing). It wasn't until 20 minutes into class that one of my students pointed it out to me, after which I proceeded to be very, very embarrassed for several minutes.
