What grade are you in?

I am struggling a little bit remembering what grades my own kids are in. Yesterday someone asked about J and I said he was in 8th grade, opps so not right, didn't I just tour the high school campus he will be going the day before. I can't stand that S is a 5th grader, and R a 2nd grader. I'm sure if asked I would get this wrong too. Don't even ask me how old I am. I just did a survey and put the wrong age. I must have way too much on my mind.
