Mr. Mysterious

As I read with my reading groups at the back table, I don't want to be interrupted by the rest of the students.  So I have them write their name in one of these columns if they have a comment (C) question (?) or an emergency (911.)  I get to them when I have a break between meeting with groups.
















Mr. Mysterious had a question today.
This has happened a few times and I still don't know who Mr. Mysterious is.
I can't wait to hear what his question is.
