You opened the map saying the sentence you had so cleverly thought of with Remus. "I solemnly swear I am up to no good."
The map opened in front of you. You remembered how much fun you guys had with this map. It took a lot of time and effort to create it.

You closed the map saying: "Mischief managed." And open the doors for the small first years to come in and start their first lesson.
"Welcome everyone. This year you will learn you the basics of defense against the dark arts also known as DADA."
