One of the nice things about having Stat Counter installed here at RotLC is that I can see the search engine searches that bring people here. It's rewarding to find that one of the most common searches is one of the many variations on the theme of "thank you note for teacher". There are obviously plenty of thoughtful people out there.
Unfortunately, I have no information about that topic on this site! The search engines direct people to my post about giving thank you notes to my students who brought me Christmas presents!
