This, my friends, is one of the dangers of having to work at home:
I have to do most of my lesson planning and grading from home. The 90 minute planning period doesn't really cut it for a new teacher. Unfortunately, if I leave my laptop unattended and my PowerPoint on Westward Expansion open, I later find slides like what you see above. Fortunately, I usually discover these slides before delivering them as notes to my students. Usually.
Thank you my darling husband for keeping me on my toes.
