One day George went back to The Burrow to get everything he needed out of his room.  when he walked in there he immediately remembered what happened to Fred.he walked in the room and saw his bed next to Fred's. He looked over to the calendar Mrs. Weasley had put up, and saw that it was May 2nd. He smiled sadly as the memories of their mischief. George went back downstairs and saw Molly. 

"What's wrong Fred?" she asked. 

"Nothing Mother," George responded. 

He knew his mother always got pranked about which one was which. 

George looked down the hallway to see the mirror Fred chipped. He smiled a sad smile and said. 

"Good job Freddie,"  

And George Fabian Weasley never went to the burrow again.
