I FOUND MY PATRONUS ANIMAL! MEET…. THE SHAME-FACED CRAB: 

JUST LOOK AT THAT FACE: 

IT IS CLEARLY NERVOUS AROUND EVERYONE AND EVERYTHING AND WAITING FOR SOMETHING BAD TO HAPPEN

LOOK AT THEM AWKWARDLY SCUTTLING OUT OF A SOCIAL SITUATION: 

LOOK AT THEM HARRUMPHING AT BEING TOLD ATTENDANCE AT A GATHERING IS MANDATORY:

LOOK AT THEM BURROW AWAY FROM THEIR PROBLEMS, PRETENDING THEY DON’T EXIST: 

I LOVE YOU, CRAB OF SHAME!
