I am just now seeing this, Jeff.  I am so very sorry for your loss. I know that I have told you this many times over the years, but I will tell you again how much influence your dad had on my decision to become a teacher. Every single time I am asked by students what made me become a teacher, I mention him as one of the reasons. I often use the name Mr. Sheets in word problems for my students. Please know that I am forever grateful for his impact in my life and my career.
