Moderator's comment before closing the thread.
This section of the forums contains this statement: If you are not a teacher, you will need to state that clearly at the top of your post.
I don't know if your status said you were a teacher before this or not. I don't usually look. If it did clearly say you were a teacher, then I'm sorry this happened. If it didn't, then I'm glad your status now says this and it's clear to all.
Any member is acting within the guidelines of this forum by requesting others follow the guidance in the sentence above. It's not personal.
Closing the thread now.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
