Today's E-Mail Treasure

 I got this e-mail from the parent of one of my new students today:

Hi Sir, 

Help me understand what transpired today that you refused to allow my student {name redacted} into your classroom. 

My response:

He arrived late to class, so the door was shut while we completed the starter activity. There was a sign on the door that asked him to wait 5 to 7 minutes to be admitted once the starter was complete. When I opened the door, he was gone.

I feel like this should resolve the issue.

I also feel about 67% confident that I have not heard the last from this parent on the issue.

But I've been wrong before. I could get lucky.

But next week is Parent Teacher Conferences, so....
